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.

Because mod is always exact, this function should have never taken a rounding mode argument. The actual implementation still has issues, which I'll look at resolving in a subsequent patch.

This commit fixes an assert that is triggered when optnone is being
added to an IR function that is already marked with minsize and optsize.

Prior to this change, OMPT had a status flag ompt_status, which could take
several values. This was due to an earlier OMPT design that had several levels
of enablement (ready, disabled, tracking state, tracking callbacks). The
current OMPT design has OMPT support either on or off.
This revision replaces ompt_status with a boolean flag ompt_enabled, which
simplifies the runtime logic for OMPT.

Based on conversations with Justin and a few others, these constructors
are really useful to have in the executable so that you can call them
from the debugger. After some measurements, these *particular* calls
aren't so problematic as to make them a good tradeoff for always inline.
Please let me know if there are other functions really needed for
debugging. The always inline attribute is a hack that we should only
really employ when it doesn't hurt.

The OMPT specification has changed. This revision brings the LLVM OpenMP
implementation up to date.
Technical overview of changes:
Previously, a public weak symbol ompt_initialize was called after the OpenMP
runtime is initialized. The new interface calls a global weak symbol ompt_tool
prior to initialization. If a tool is present, ompt_tool returns a pointer to
a function that matches the signature for ompt_initialize. After OpenMP is
initialized the function pointer is called to initialize a tool.
Knowing that OMPT will be enabled before initialization allows OMPT support to
be initialized as part of initialization instead of back patching
initialization of OMPT support after the fact.
Post OpenMP initialization support has been generalized moves from
ompt-specific.c into ompt-general.c, since the OMPT initialization logic is no
longer implementation specific.

The definition of the DivergenceAnalysis pass was in a CPP
file and wasn't accessible to users of the analysis to get it
through "getAnalysis<>()".
This patch extracts the definition into a separate header that
can be used by users of the analysis to fetch the results.

This is more consistent with OutputSection. This is also part of removing
the "Chunk" term from the ELF linker, since we just have input/output sections
and program headers.

evaluate whether 'readonly' or 'readnone' apply to a given function.
This both reduces indentation and will make it easy to share the logic
with a new pass manager implementation.

The ISD::FPOW and ISD::FSINCOS opcodes default to Legal, but there
is no legal instruction for those on SystemZ. This could cause
LLVM internal errors. Fixed by setting the operation action to
Expand for those opcodes.
Also added test cases for all other LLVM IR intrinsics that should
generate a library call. (Those already work correctly since the
default operation action is fine.)

- rename "Failures" window to "Completed Tests"
- Remove the extra lock that I incorrectly added to the ResultsFormatter as it already had one
- Init the curses GUI with the right number of jobs when handling the "intialize" event
- tear down the curses GUI when tests complete

pthread is in LLDB_SYSTEM_LIBS so there's no need to explicitly add it to the link.

A missing return statement that previously did not have a visibly negative
effect caused after some data-structure changes in r248024 multi-dimensional
accesses to be modeled both multi-dimensional as well as linearized. This
commit adds the missing return to avoid the incorrect double modeling as
well as the compile time increases it caused.

If storing multiple FP constants, some subset of the stores
would be replaced with integers due to visit order, so
MergeConsecutiveStores would only partially merge
these.
