[OpenMP] Avoid VLAs for some reductions on array sections
In some cases the compiler can deduce the length of an array section
as constants. With this information, VLAs can be avoided in place of
a constant sized array or even a scalar value if the length is 1.
Example:
int a[4], b[2];
pragma omp parallel reduction(+: a[1:2], b[1:1])
{ }
For chained array sections, this optimization is restricted to cases
where all array sections except the last have a constant length 1.
This trivially guarantees that there are no holes in the memory region
that needs to be privatized.
Example:
int c[3][4];

Make x86 __ehhandler comdat if parent function is
Summary:
This change comes from using lld for i686-windows-msvc. Before this change, lld
emits an error of:
error: relocation against symbol in discarded section: .xdata
It's possible that this could be addressed in lld, but I think this change is
reasonable on its own.
At a high level, this is being generated:
A (.text comdat) -> B (.text) -> C (.xdata comdat)
Where A is a C++ inline function, which references B, an exception handler
thunk, which references C, the exception handling info.
With this structure, lld will error when applying relocations to B if the C it
references has been discarded (some other C has been selected).
This change checks if A is comdat, and if so places the exception registration
thunk (B) in the comdata group of A (and B).
It appears that MSVC makes the __ehhandler function comdat.
Is it possible that duplicate thunks are being emitted into the final binary
with other linkers, or are they stripping the unused thunks?

[tsan] Add Mutex annotation flag for constant-initialized __tsan_mutex_linker_init behavior
Add a new flag, __tsan_mutex_not_static, which has the opposite sense
of __tsan_mutex_linker_init. When the new __tsan_mutex_not_static flag
is passed to __tsan_mutex_destroy, tsan ignores the destruction unless
the mutex was also created with the __tsan_mutex_not_static flag.
This is useful for constructors that otherwise woud set
__tsan_mutex_linker_init but cannot, because they are declared constexpr.
Google has a custom mutex with two constructors, a "linker initialized"
constructor that relies on zero-initialization and sets
__tsan_mutex_linker_init, and a normal one which sets no tsan flags.
The "linker initialized" constructor is morally constexpr, but we can't
declare it constexpr because of the need to call into tsan as a side effect.
With this new flag, the normal c'tor can set __tsan_mutex_not_static,
the "linker initialized" constructor can rely on tsan's lazy initialization,
and __tsan_mutex_destroy can still handle both cases correctly.

Logging: Make sure logging machinery is in a consistent state after forking
Summary:
We had a bug where if we had forked (in the ProcessLauncherPosixFork)
while another thread was writing a log message, we would deadlock. This
happened because the fork child inherited the locked log rwmutex, which
would never get unlocked. This meant the child got stuck trying to
disable all log channels.
The bug existed for a while but only started being apparent after
D37930, which started using ThreadLauncher (which uses logging) instead
of std::thread (which does not) for launching TaskPool threads.
The fix is to use pthread_atfork to make sure noone is writing a log
message while we are forking.

[X86] Replace custom scalar integer absolute matching with ISD::ABS lowering.
x86 has its own copy of integer absolute pattern matching to combine directly to a SUB+CMOV.
This patch removes the x86 combine and adds custom lowering support for ISD::ABS instead, allowing us to use the DAGCombiner version.
Additional test cases are already covered by iabs.ll (rL315706 and rL315711).

[MergeFunctions] Don't blindly RAUW a GlobalValue with a ConstantExpr.
MergeFunctions uses (through FunctionComparator) a map of GlobalValues
to identifiers because it needs to compare functions and globals
do not have an inherent total order. Thus, FunctionComparator
(through GlobalNumberState) has a ValueMap<GlobalValue *>.
r315852 added a RAUW on globals that may have been previously
encountered by the FunctionComparator, which would replace
a GlobalValue * key with a ConstantExpr *, which is illegal.
This commit adjusts that code path to remove the function being
replaced from the ValueMap as well.

[CMake] Allow parent projects to use in-source builds
LLVM checks if it is performing an in-source build and then stop the
build. However, this check is also triggered if LLVM is being build as
part of a parent project, which prevents the parent project itself from
using in-source builds. For example, CMake allows a parent project to
specify the output of its subproject:
add_subdirectory(llvm llvm_build)
This tells CMake to conduct an out-tree build of LLVM, which without
this patch will still fails because what is being tested is the parent
project, not LLVM. This is fixed by using the "CURRENT" variable, which
is only concerned by the CMakeLists that is actually bein processed at
the moment.
Tests:
Ran `make check-llvm`.

LineCoverageIterator makes it easy for clients of coverage data to

iteration logic is tricky enough that it really pays not to have
