Skipped tests can be dropped from xUnit reports if either
the name or the skip reason matches one of a given set of
regular expression patterns (via re.search(), not re.match()).
New formatter option for the xunit formatter:
--ignore-skip-matching-reason and
--ignore-skip-matching-name
Both are results-formatter options.

Previously the code added an extra nullptr entry to a static array and then created an ArrayRef with a size one less than the static array. If there were no other entries the array would just contain the nullptr and the ArrayRef would be crated with size 0.
Instead, put the right number of entries in the array and explicitly emit 'None' if the size would be 0. This allows the static array constructor of makeArrayRef to be used.

Before, clang's internal assembler would reject the inline asm in clang's
Intrin.h. To make sure this doesn't happen for other Intrin.h functions using
__asm__ blocks, add 32-bit and 64-bit codegen tests for Intrin.h.
Sadly, these tests discovered that __readcr3 and __writecr3 have bad
implementations in 64-bit builds. This will have to be fixed in a follow-up.

Added key press handling and a first responder system and the ability for windows that can be first responders to be selected and have key presses routed to the first resonder, delegates and also travel up the parent chain.
Remove the temp file that was being created.

Summary:
We should either require the DT info to be available, or check if it's
available in every place we use DT (and we already miss such check in
one place, which causes failures in some cases). As other loop passes
preserve DT and it's usually available, it makes sense to just require
it here.
There is no regression test, because the bug only shows up if pass
manager decides to clean DT info right before LoopUnswitch. If
loop-unswitch is run separately, DT is available, so bug isn't exposed.

The parallel test runner now sends the terminate event to the formatter
(if there is one) after the parallel test runs but before dumping anything
to stdout/stderr at the end of the run. This allows the existing
stdout/stderr summary reporting to co-exist nicely with a formatter like
the test_results.Curses that otherwise clobbers the screen.

This is an LLD extension to MSVC link.exe command line. MSVC linker
does not write symbol tables for executables. We do unless no /debug
option is given.
There's a situation that we want to enable debug info but don't want
to emit the symbol table. One example is when we are comparing output
file size. With this patch, you can tell the linker to not create
a symbol table by just specifying /nosymtab.

We know that an argmemonly function can only access memory pointed to by it's pointer arguments. Rather than needing to consider all possible stores as aliasing (as we do for a readonly function), we can only consider the aliasing of the pointer arguments.
Note that this change only addresses hoisting. I'm thinking about how to address speculation safety as well, but that will be a different change.
FYI, argmemonly disallows accessing memory through non-pointer typed arguments.

Turns out that not every basic block is guaranteed to have a node within the DominatorTree. This is really hard to trigger, but the test case from the PR managed to do so. There's active discussion continuing about what documentation and/or invariants needed cleaned up.

This change introduces a check-libomp target which is based upon llvm's lit
test infrastructure. Each test (generated from the University of Houston's
OpenMP testsuite) is compiled and then run. For each test, an exit status of 0
indicates success and non-zero indicates failure. This way, FileCheck is not
needed. I've added a bit of logic to generate symlinks (libiomp5 and libgomp)
in the build tree so that gcc can be tested as well. When building out-of-
tree builds, the user will have to provide llvm-lit either by specifying
-DLIBOMP_LLVM_LIT_EXECUTABLE or having llvm-lit in their PATH.

This patch adds support for combining patterns such as (FMUL(FADD(1.0, x), y)) and (FMUL(FSUB(x, 1.0), y)) to their FMA equivalents.
This is useful in particular for linear interpolation cases such as (FADD(FMUL(x, t), FMUL(y, FSUB(1.0, t))))

The vext pseudo-instruction takes the number of elements that need to be
extracted, not the number of bytes. Hence, use the number of elements
directly instead of scaling them with a factor.

We prefer setting these in our .clang-format file as the macros change over
time. (Also, the code was setting MacroBlockBegin twice and didn't set
MacroBlockEnd, so it wasn't doing what it tried to do anyways.)

std::distance(C->Relocs.end(), C->Relocs.begin()) is the same as NumRelocs
which is already added to the hash value. What we are missing here is the
section size.

We're currently losing any fast-math flags when synthesizing fcmps for
min/max reductions. In LV, make sure we copy over the scalar inst's
flags. In LoopUtils, we know we only ever match patterns with
hasUnsafeAlgebra, so apply that to any synthesized ops.
