Some of the JIT tests began failing with "[llvm] r266663 - [Orc] Re-commit
r266581 with fixes for MSVC, and format cleanups." on powerpc64 big endian.
To get the buildbots running I am marking these as UNSUPPORTED for now.
If this is fixed remove the UNSUPPORTED flag "powerpc64-unknown-linux-gnu".
In r267516 I marked these as XFAIL but they succeed on some of the bots
on stage1.

When passed in via filename, this test will fail if the path to the test
has the strings "f1" and "f2" in somewhere. Pass the file through stdin
to prevent test failures due to coincidences in path names.

When SimplifyCFG merges identical instructions from both sides of a diamond, it
can preserve !llvm.mem.parallel_loop_access (as it does with most of the other
metadata). There's no real data or control dependency change in this case.

I really thought we were doing this already, but we were not. Given this input:
void Test(int *res, int *c, int *d, int *p) {
for (int i = 0; i < 16; i++)
res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
}
we did not vectorize the loop. Even with "assume_safety" the check that we
don't if-convert conditionally-executed loads (to protect against
data-dependent deferenceability) was not elided.
One subtlety: As implemented, it will still prefer to use a masked-load
instrinsic (given target support) over the speculated load. The choice here
seems architecture specific; the best option depends on how expensive the
masked load is compared to a regular load. Ideally, using the masked load still
reduces unnecessary memory traffic, and so should be preferred. If we'd rather
do it the other way, flipping the order of the checks is easy.
The LangRef is updated to make explicit that llvm.mem.parallel_loop_access also
implies that if conversion is okay.

This unifies the definition of _LIBUNWIND_BUILD_SJLJ_APIS. It also further
generalises the definition to allow building these APIs on non-Apple targets
when `-fsjlj-excceptions` is used. The header is now clean of macros which
expand to defined checks.

rL267291 introduces a lot regression on arm-linux LLDB testsuite.
This patch fixes half of them. I am merging it under already revied android counterpart.
Another patch fixing rest of the issue will follow this commit.

Pass all of the state we need around as arguments, so that these
functions are easier to reuse. There is one part of this that is
unusual: we pass around a functor to look up a DomTree for a function.
This will be a necessary abstraction when we try to use this code in
both the legacy and the new pass manager.

Autoconf used to support setting LLVM_VERSION_INFO and there is some code filtered around llvm in Support/CommandLine.cpp and LTO/LTOCodeGenerator.cpp that uses it if it is set.
We also shouldn't be explicitly setting it as a define on llvm-shlib. It is pointless there because there is no code using it in llvm-shlib, and it is better to have it as part of the generated config.h so that it is available everywhere.

The SparcV8 fneg and fabs instructions interestingly come only in a
single-float variant. Since the sign bit is always the topmost bit no
matter what size float it is, you simply operate on the high
subregister, as if it were a single float.
However, the layout of double-floats in the float registers is reversed
on little-endian CPUs, so that the high bits are in the second
subregister, rather than the first.
Thus, this expansion must check the endianness to use the correct
subregister.

This fixes fails in test/msan/dlerror.cc - when real dlerror calls strcmp,
our strcmp interceptor now skips poison checking, since it's called in
interceptor context. Strictly speaking, only the dlerror change is
necessary to fix the fail, but let's also change the other two just in case.

This patch is what was the "instcombine" portion of D14185, with an additional
test added (see julia_pseudovec in test/Transforms/InstCombine/insert-val-extract-elem.ll).
The patch causes instcombine to replace sequences of extractelement-insertvalue-store
that act essentially like a bitcast followed by a store.

Currently, clang-cl always uses Windows style for unquoting, and clang always
uses POSIX style for unquoting.
With this flag, it's possible to change these defaults.
In general, response file quoting should match the shell the response file is
used in. On Windows, it's possible to run clang-cl in a bash shell, or clang in
cmd.exe, so a flag for overriding the default behavior is natural there.
On non-Windows, Windows quoting probably never makes sense (except maybe in
Wine), but having clang-cl behave differently based on the host OS seems
strange too. So require that people who want to use posix-style response
files with clang-cl on non-Windows pass --rsp-quoting=posix.
