[ptr-traits] Provide a real MCFragment address for the sentinel instead
of casting the integer '4' to such a pointer. There is no reason to
expect '4' to be a portable or reliable pointer of this form. The only
reason this ever worked is because the PointerIntPair that this actually
gets used with has an artificially *low* presumed alignment that allowed
it to work. When the alignment of PointerIntPair is derived from the
actual type's alignment, the asserts start firing on this pointer. I'm
amazed we never managed to do anything that triggered the alignment
sanitizer with it, as this is just flat out UB.
If folks dislike this approach to providing a sentinel fragment address,
there are a myriad of other alternatives, suggestions welcome. But this
one has the distinct advantage of not requiring the friend dance of
ilist's sentinel (which I'll point out is *also* in play for
MCFragment!) and seems to be using a nicely provided facility in
MCFragment to establish just such dummy nodes.

This adds support for the MCU psABI in a way different from r251223 and r251224,
basically reverting most of these two patches. The problem with the approach
taken in r251223/4 is that it only handled libcalls that originated from the backend.
However, the mid-end also inserts quite a few libcalls and assumes these use the
platform's default calling convention.
The previous patch tried to insert inregs when necessary both in the FE and,
somewhat hackily, in the CG. Instead, we now define a new default calling convention
for the MCU, which doesn't use inreg marking at all, similarly to what x86-64 does.

[lit] Implement support of per test timeout in lit.
This should work with ShTest (executed externally or internally) and GTest
test formats.
To set the timeout a new option ``--timeout=`` has
been added which specifies the maximum run time of an individual test
in seconds. By default this 0 which causes no timeout to be enforced.
The timeout can also be set from a lit configuration file by modifying
the ``lit_config.maxIndividualTestTime`` property.
To implement a timeout we now require the psutil Python module if a
timeout is requested. This dependency is confined to the newly added
``lit.util.killProcessAndChildren()``. A note has been added into the
TODO document describing how we can remove the dependency on the
``pustil`` module in the future. It would be nice to remove this
immediately but that is a lot more work and Daniel Dunbar believes it is
better that we get a working implementation first and then improve it.
To avoid breaking the existing behaviour the psutil module will not be
imported if no timeout is requested.
The included testcases are derived from test cases provided by
Jonathan Roelofs which were in an previous attempt to add a per test
timeout to lit (http://reviews.llvm.org/D6584). Thanks Jonathan!

[attrs] Extract the pure inference of function attributes into
a standalone pass.
There is no call graph or even interesting analysis for this part of
function attributes -- it is literally inferring attributes based on the
target library identification. As such, we can do it using a much
simpler module pass that just walks the declarations. This can also
happen much earlier in the pass pipeline which has benefits for any
number of other passes.
In the process, I've cleaned up one particular aspect of the logic which
was necessary in order to separate the two passes cleanly. It now counts
inferred attributes independently rather than just counting all the
inferred attributes as one, and the counts are more clearly explained.
The two test cases we had for this code path are both ... woefully
inadequate and copies of each other. I've kept the superset test and
updated it. We need more testing here, but I had to pick somewhere to
stop fixing everything broken I saw here.

[gc.statepoint] Change gc.statepoint intrinsic's return type to token type instead of i32 type
Summary: This patch changes gc.statepoint intrinsic's return type to token type instead of i32 type. Using token types could prevent LLVM to merge different gc.statepoint nodes into PHI nodes and cause further problems with gc relocations. The patch also changes the way on how gc.relocate and gc.result look for their corresponding gc.statepoint on unwind path. The current implementation uses the selector value extracted from a { i8*, i32 } landingpad as a hook to find the gc.statepoint, while the patch directly uses a token type landingpad (http://reviews.llvm.org/D15405) to find the gc.statepoint.

[InstCombine] transform more extract/insert pairs into shuffles (PR2109)
This is an extension of the shuffle combining from r203229:
http://reviews.llvm.org/rL203229
The idea is to widen a short input vector with undef elements so the
existing shuffle transform for extract/insert can kick in.
The motivation is to finally solve PR2109:
https://llvm.org/bugs/show_bug.cgi?id=2109
For that example, the IR becomes:
%1 = bitcast <2 x i32>* %P to <2 x float>*
%ld1 = load <2 x float>, <2 x float>* %1, align 8
%2 = shufflevector <2 x float> %ld1, <2 x float> undef, <4 x i32> <i32 0, i32 1, i32 undef, i32 undef>
%i2 = shufflevector <4 x float> %A, <4 x float> %2, <4 x i32> <i32 0, i32 1, i32 4, i32 5>
ret <4 x float> %i2
And x86 SSE output improves from:
movq (%rdi), %xmm1 ## xmm1 = mem[0],zero
movdqa %xmm1, %xmm2
shufps $229, %xmm2, %xmm2 ## xmm2 = xmm2[1,1,2,3]
shufps $48, %xmm0, %xmm1 ## xmm1 = xmm1[0,0],xmm0[3,0]
shufps $132, %xmm1, %xmm0 ## xmm0 = xmm0[0,1],xmm1[0,2]
shufps $32, %xmm0, %xmm2 ## xmm2 = xmm2[0,0],xmm0[2,0]
shufps $36, %xmm2, %xmm0 ## xmm0 = xmm0[0,1],xmm2[2,0]
retq
To the almost optimal:
movhpd (%rdi), %xmm0
Note: There's a tension in the existing transform related to generating
arbitrary shufflevector masks. We avoid that in other places in InstCombine
because we're scared that codegen can't handle strange masks, but it looks
like we're ok with producing those here. I purposely chose weird insert/extract
indexes for the regression tests to see the effect in these cases.
For PowerPC+Altivec, AArch64, and X86+SSE/AVX, I think the codegen is equal or
better for these examples.

LLVM CodeView library
Summary: This diff is the initial implementation of the LLVM CodeView library. There is much more work to be done, namely a CodeView dumper and tests. This patch should help others make progress on the LLVM->CodeView debug info emission while I continue with the implementation of the dumper and tests.
This library implements support for emitting debug info in the CodeView format. This phase of the implementation only includes support for CodeView type records. Clients that need to emit type records will use a class derived from TypeTableBuilder. TypeTableBuilder provides member functions for writing each kind of type record; each of these functions eventually calls the writeRecord virtual function to emit the actual bits of the record. Derived classes override writeRecord to implement the folding of duplicate records and the actual emission to the appropriate destination. LLVMCodeView provides MemoryTypeTableBuilder, which creates the table in memory. In the future, other classes derived from TypeTableBuilder will write to other destinations, such as the type stream in a PDB.
The rest of the types in LLVMCodeView define the actual CodeView type records and all of the supporting enums and other types used in the type records. The TypeIndex class is of particular interest, because it is used by clients as a handle to a type in the type table.
The library provides a relatively low-level interface based on the actual on-disk format of CodeView. For example, type records refer to other type records by TypeIndex, rather than by an actual pointer to the referent record. This allows clients to emit type records one at a time, rather than having to keep the entire transitive closure of type records in memory until everything has been emitted. At some point, having a higher-level interface layered on top of this one may be useful for debuggers and other tools that want a more holistic view of the debug info. The lower-level interface should be sufficient for compilers and linkers to do the debug info manipulation that they need to do efficiently.

AVX-512: Kreg set 0/1 optimization
The patterns that set a mask register to 0/1
KXOR %kn, %kn, %kn / KXNOR %kn, %kn, %kn
are replaced with
KXOR %k0, %k0, %kn / KXNOR %k0, %k0, %kn - AVX-512 targets optimization.
KNL does not recognize dependency-breaking idioms for mask registers,
so kxnor %k1, %k1, %k2 has a RAW dependence on %k1.
Using %k0 as the undef input register is a performance heuristic based
on the assumption that %k0 is used less frequently than the other mask
registers, since it is not usable as a write mask.
