methods.
Patch changes return type of FunctionComparator::compare() and
FunctionComparator::compare(const BasicBlock*, const BasicBlock*)
methods from bool (equal or not) to {-1, 0, 1} (less, equal, great).
This patch belongs to patch series that improves MergeFunctions
performance time from O(N*N) to O(N*log(N)).

We handle this by spilling the whole thing to the stack and doing the
insertion as a store.
PR19492. This happens in real code because the vectorizer creates v2i128 when AVX is enabled.

This broke the arm bots. The crash can be reproduced on X86 by running.

Storage Class 3 is static storage. These symbols need to be marked as external
(storage class 2) so that they can be referenced. Note that this external is
not the same as ELF "external" visibility, which is indicated by DLL Storage
Class (i.e. __declspec(dllexport) or __declspec(dllimport)).

This patch adds ISel patterns to select SSE3/AVX ADDSUB instructions
from a sequence of "vadd + vsub + blend".
Example:
///
typedef float float4 __attribute__((ext_vector_type(4)));
float4 foo(float4 A, float4 B) {
float4 X = A - B;
float4 Y = A + B;
return (float4){X[0], Y[1], X[2], Y[3]};
}
///
Before this patch, (with flag -mcpu=corei7) llc produced the following
assembly sequence:
movaps %xmm0, %xmm2
addps %xmm1, %xmm2
subps %xmm1, %xmm0
blendps $10, %xmm2, %xmm0
With this patch, we now get a single
addsubps %xmm1, %xmm0

We didn't properly implement support for the sized integer suffixes.
Suffixes like i16 were essentially ignored instead of mapping them to
the appropriately sized integer type.
This fixes PR20008.

When a stub reported $#00 (unsupported) for _M and _m
packets, the unsupported response was not handled and
the client then marked the _M/_m commands as definitely
supported. However, they would always fail, preventing
lldb's fallback InferiorCallMmap-based allocation strategy
from being used to attempt to allocate memory in the inferior
process space.

std::recursive_mutex are not available on MinGW and breaks the
builder. Revert to using a function local static and sys::Mutex
just to get the tree green until we figure out a better solution.

The version information for Visual Studio is spread over multiple variables.
The newer Windows SDK has started making use of some of the extended versioning
variables that were previously undefined. Enhance our compatibility definitions
for these cases.
_MSC_VER is defined to be the Major * 100 + Minor. _MSC_FULL_VER is defined to
be Major * 10000000 + Minor * 100000 + Build. And _MSC_BUILD is the build
revision of the compiler.
Extend the -fmsc-version option in a compatible manner. If the value is the
previous form of MMmm, then we assume that the build number is 0. Otherwise, a
specific build number may be passed by using the form MMmmbbbbb. Due to
bitwidth limitations of the option, it is currently not possible to define a
revision value.
The version information can be passed as either the decimal encoded value
(_MSC_FULL_VER or _MSC_VER) or as a dot-delimited value.
The change to the TextDiagnostic is to deal with the updated encoding of the
version information.

It's more flexible and arguably better layering to set flags to modify
compiling for diagnostics in the CC1 job themselves, rather than
tweaking the driver flags and letting them propagate.
There is one visible change this causes: crash report files will now
get preprocessed names (.i and friends).

These tests relied on information that was only available for clang
builds that included asserts. Fix these tests to lift that restriction.

the tool is given multiple files. Also fix the same issue with Mach-O
universal files. And fix the newline spacing to separate the output
in these cases.

This refactors the emission of dynamic_cast and typeid expressions so
that ABI specific knowledge lives in appropriate places. There are
quite a few benefits for having the two implementations share a common
core like sharing logic for optimization opportunities.
While we are at it, clean up the tests.

This reverts commit 1f502bd9d7d2c1f98ad93a09ffe435e11a95aedd, due to
GCC / MinGW's lack of support for C++11 threading.
It's possible this will go back in after we come up with a
reasonable solution.

This patch enables LLVM to emit Win64-native unwind info rather than
DWARF CFI. It handles all corner cases (I hope), including stack
realignment.
Because the unwind info is not flexible enough to describe stack frames
with a gap of unknown size in the middle, such as the one caused by
stack realignment, I modified register spilling code to place all spills
into the fixed frame slots, so that they can be accessed relative to the
frame pointer.

Summary:
Different range metadata can lead to different optimizations in later
passes, possibly breaking the semantics of the merged function. So range
metadata must be taken into consideration when comparing Load
instructions.
Thanks!
