[SelectionDAG] Swap commutative binops before constant-based folding
In searching for a fix for the underlying code-quality bug highlighted by
r246937 (that SDAG simplification can lead to us generating an ISD::OR node
with a constant zero LHS), I ran across this:
We generically canonicalize commutative binary-operation nodes in SDAG getNode
so that, if only one operand is a constant, it will be on the RHS. However, we
were doing this only after a bunch of constant-based simplification checks that
all assume this canonical form (that any constant will be on the RHS). Moving
the operand-swapping canonicalization prior to these checks seems like the
right thing to do (and, as it turns out, causes SDAG to completely fold away the
computation in test/CodeGen/ARM/2012-11-14-subs_carry.ll, just like InstCombine
would do).

[cmake] rework LLVM_LINK_LLVM_DYLIB option handling
Summary:
This diff attempts to address the concerns raised in
http://reviews.llvm.org/D12488.
We introduce a new USE_SHARED option to llvm_config,
which, if set, causes the target to be linked against
libLLVM.
add_llvm_utility now uniformly disables linking against
libLLVM. These utilities are not intended for distribution,
and this keeps the option handling more centralised.
llvm-shlib is now processes before any other "tools"
subdirectories, ensuring the libLLVM target is defined
before its dependents.
One main difference from what was requested: llvm_config
does not prune LLVM_DYLIB_COMPONENTS from the components
passed into explicit_llvm_config. This is because the "all"
component does something special, adding additional
libraries (namely libLTO). Adding the component libraries
after libLLVM should not be a problem, as symbols will be
resolved in libLLVM first.
Finally, I'm not really happy with the
DISABLE_LLVM_LINK_LLVM option, but I'm not sure of a
better way to get the following:
- link all tools and shared libraries to libLLVM if
LLVM_LINK_LLVM_DYLIB is set
- some way of explicitly *not* doing so for utilities
and libLLVM itself
Suggestions for improvement here are particularly welcome.

[PowerPC] Try harder to find a base+offset when looking for consecutive accesses
When forming permutation-based unaligned vector loads, we need to know whether
it is valid to read ahead of the requested address by a full vector length.
Doing so is more efficient (and allows for more CSE with later loads), but
could trigger a page fault if invalid. To determine validity, we look for other
loads in the same block that access the relevant address range.
The relevant point here is that we need to do this as part of the process of
forming permutation-based vector loads, and this happens quite early in the
SDAG pipeline - specifically before many of the address calculations are fully
canonicalized. As a result, we need to try harder to recognize base+offset
address computations, because they still might appear as chain of adds
(base+offset+offset, for example). To account for this, we'll look through
chains of adds, accumulating the constant offsets.

[RewriteStatepointsForGC] Strengthen invariants around BDVs
As a first step towards a new implementation of the base pointer inference algorithm, introduce an abstraction for BDVs, strengthen the assertions around them, and rewrite the BDV relation code in terms of the abstraction which includes an explicit notion of whether the BDV is also a base. The later is motivated by the fact we had a bug where insertelement was always assumed to be a base pointer even though the BDV code knew it wasn't. The strengthened assertions in this patch would have caught that bug.
The next step will be to separate the DefiningValueMap into a BDV use list cache (entirely within findBasePointers) and a base pointer cache. Having the former will allow me to use a deterministic visit order when visiting BDVs in the inference algorithm and remove a bunch of ordering related hacks. Before actually doing the last step, I'm likely going to extend the lattice with a 'BaseN' (seen only base inputs) state so that I can kill the post process optimization step.

Try to clarify the semantics of fptrunc
* ``the value cannot fit within the destination type`` is ambiguous.
It could mean overflow, underflow (not in the IEEE-754 sense) or a
result that cannot be exactly represented and requires rounding or it
could mean some combination of these. The semantics now state it means
overflow **only**.
* Using "truncation" in the semantics is very misleading given that it
doesn't necessarily truncate (i.e. round to zero). For example on
x86_64 with SSE2 this is currently mapped to cvtsd2ss instruction
who's rounding behaviour is dependent on the MXCSR register which
is usually set to round to nearest even by default. The semantics
now state that the rounding mode is undefined.

Tweak llvm/test/tools/gold/X86/parallel.ll to run with pthread-unaware ld.gold on Linux.
If ld.gold is configured without --enable-thread, ld.gold might not load libpthread.so.
Preloading LLVMgold.so loads also libpthread.so.

[MergeFuncs] Efficiently defer functions on merge
Summary:
This patch introduces a side table in Merge Functions to
efficiently remove functions from the function set when functions
they refer to are merged. Previously these functions would need to
be compared lg(N) times to find the appropriate FunctionNode in the
tree to defer. With the recent determinism changes, this comparison
is more expensive. In addition, the removal function would not always
actually remove the function from the set (i.e. after remove(F),
there would sometimes still be a node in the tree which contains F).
With these changes, these functions are properly deferred, and so more
functions can be merged. In addition, when there are many merged
functions (and thus more deferred functions), there is a speedup:
chromium: 48678 merged -> 49380 merged; 6.58s -> 5.49s
libxul.so: 41004 merged -> 41030 merged; 8.02s -> 6.94s
mysqld: 1607 merged -> 1607 merged (same); 0.215s -> 0.212s (probably noise)

[libFuzzer] deprecate the -tokens flag. This was a bad idea because the corpus with this flag contains encrypted inputs, not the real inputs, which complicates interoperation with other fuzzers. Instead we'll need to implement AFL dictionary support

[X86] Require 32-byte alignment for 32-byte VMOVNTs.
We used to accept (and even test, and generate) 16-byte alignment
for 32-byte nontemporal stores, but they require 32-byte alignment,
per SDM. Found by inspection.
Instead of hardcoding 16 in the patfrag, check for natural alignment.
Also fix the autoupgrade and the various tests.
Also, use explicit -mattr instead of -mcpu: I stared at the output
several minutes wondering why I get 2x movntps for the unaligned
case (which is the ideal output, but needs some work: see FIXME),
until I remembered corei7-avx implies +slow-unaligned-mem-32.
