Avoid calls to dumpPassInfo and RegionBase<Tr>::getNameStr() in RGPassManager if
-debug-pass is not specified, as the string is only used when dumping pass
information. There is a big cost of determining the name in
ReginBase<Tr>:getNameStr() if the region's entry or exit block doesn't have a
name. This is the case for the Release build, as names are not preserved by the
front-end.
RegionPass is mainly used by Polly, resulting in long compile time for one file
of a customer application with the Release build (1m24s) vs Release+Asserts
build (10s) when Polly is used. With this change, the compile time with the
Release build went down to 8s.

[ConstantRange] Teach multiply to be cleverer about signed ranges.
Multiplication is not dependent on signedness, so just treating
all input ranges as unsigned is not incorrect. However it will cause
overly pessimistic ranges (such as full-set) when used with signed
negative values.
Teach multiply to try to interpret its inputs as both signed and
unsigned, and then to take the most specific (smallest population)
as its result.

for(int i=0;i<N;i++)
for(int j=0;j<N;j++)
A[j][i] = A[j][i]+B[j][i];
is interchanged to -

for(int i=0;i<N;i++)
A[j][i] = A[j][i]+B[j][i];
This pass is currently disabled by default.
To give a brief introduction it consists of 3 stages-
LoopInterchangeLegality : Checks the legality of loop interchange based on Dependency matrix.
LoopInterchangeProfitability: A very basic heuristic has been added to check for profitibility. This will evolve over time.
LoopInterchangeTransform : Which does the actual transform.
LNT Performance tests shows improvement in Polybench/linear-algebra/kernels/mvt and Polybench/linear-algebra/kernels/gemver becnmarks.

1) Add support for reductions and lcssa phi.
2) Improve profitability model.
3) Improve loop selection algorithm to select best loop for interchange. Currently the innermost loop is selected for interchange.
4) Improve compile time regression found in llvm lnt due to this pass.

[AVX] Lower / fast-isel scalar FP selects into VBLENDV instructions (PR22483)
This patch reduces code size for all AVX targets and increases speed for some chips.
SSE 4.1 introduced the useless (see code comments) 2-register form of BLENDV and
only in the packed float/double flavors.
AVX subsequently made the instruction useful by adding a 4-register operand form.
So we just need to paper over the lack of scalar forms of this instruction, complicate
the code to choose float or double forms, and use blendv on scalars since all FP is in
xmm registers anyway.
This gives us an approximately 50% speed up for a blendv microbenchmark sequence
on SandyBridge and Haswell:
blendv : 29.73 cycles/iter
logic : 43.15 cycles/iter
No new test cases with this patch because:
1. fast-isel-select-sse.ll tests the positive side for regular X86 lowering and fast-isel
2. sse-minmax.ll and fp-select-cmp-and.ll confirm that we're not firing for scalar selects without AVX
3. fp-select-cmp-and.ll and logical-load-fold.ll confirm that we're not firing for scalar selects with constants.

[ARM] Enable vector extload combine for legal types.
This commit enables forming vector extloads for ARM.
It only does so for legal types, and when we can't fold the extension
in a wide/long form of the user instruction.
Enabling it for larger types isn't as good an idea on ARM as it is on
X86, because:
- we pretend that extloads are legal, but end up generating vld+vmov
- we have instructions like vld {dN, dM}, which can't be generated
when we "manually expand" extloads to vld+vmov.
For legal types, the combine doesn't fire that often: in the
integration tests only in a big endian testcase, where it removes a

[Windows] Implement PrintStackTrace(FILE*)
llvm::sys::PrintBacktrace(FILE*) is supposed to print a backtrace
of the current thread given the current PC. This function was
unimplemented on Windows, and instead the only time we could
print a backtrace was as the result of an exception through
LLVMUnhandledExceptionFilter.
This patch implements backtracing of self by using
RtlCaptureContext to get a CONTEXT for the current thread, and
moving the printing and StackWalk64 code to a common method that
printing own stack trace and printing stack trace of an exception
can use.

This commit adds code to emit DIE trees that have been pruned from the
parts that haven't been marked as kept in the previous pass.
It works by 'cloning' the input DIE tree (as read by libDebugInfoDwarf)
into a tree of DIE objects. Cloning the DIEs means essentially cloning
their attributes. The code in this commit does only handle scalar and
block attributes (scalar because they are trivial, blocks because they
can't be easily replaced by a scalr placeholder), all the other ones
are replaced by placeholder zero values and will be handled in
further commits.
The added tests mostly check that the DIE tree has the correct layout and
also verify that a few chosen scalar and block attributes correctly make
their way into the output.

DWARFFormValue: Add getAsSignedConstant method.
The implementation accepts explicitely signed forms (DW_FORM_sdata),
but also unsigned forms as long as they fit in an int64_t.

Teach DIEInteger to emit FORM_strp and FORM_ref_addr attributes.
To be used/tested by llvm-dsymutil. (llvm-dsymutil does a 'static' link,
no need for relocations for most things, so it'll just emit raw integers
for most attributes)

Make the DWARFAbbreviationDeclaration::AttributeSpec type public.
It was already exposed through the iterators anyway.

Expand variables when evaluating absolute expressions.
This allows for variables to be used in .size.
This matches gnu AS functionality.

Update LangRef for getelementptr explicit type changes
Here's a rough/first draft - it at least hits the actual textual IR
examples and some of the phrasing. It's probably worth a full pass over,
but I'm not sure how much these docs should reflect the strange
intermediate state we're in anyway.
Totally open to lots of review/feedback/suggestions.
