Any unsuccessful llvm.type.checked.load devirtualizations will be translated
into uses of llvm.type.test, so we need to add the resulting llvm.type.test
intrinsics to the function summaries so that the LowerTypeTests pass will
export them.

Now print diagnostics for static, virtual, inline, volatile, and const
differences in methods. Also use DeclarationName instead of IdentifierInfo

We can now end up in situations where we initiate LiveIntervalUnion
queries with different SubRanges against the same register unit, so the
assert() no longer holds in all cases. Just recalculate now when we know
the cache is out of date.

Summary:
This change adds an arch-specific subdirectory in <ResourceDir>/lib/<OS>
to the linker search path. This path also gets added as '-rpath' for
native compilation if a runtime is linked in as a shared object. This
allows arch-specific libraries to be installed alongside clang.

Some repos are not git repos, so git is expected
to fail. These errors should not go to stderr,
because Xcode interprets them as failures.

These are simplified variants of the current G_SEQUENCE and G_EXTRACT, which
assume the individual parts will be contiguous, homogeneous, and occupy the
entirity of the larger register. This makes reasoning about them much easer
since you only have to look at the first register being merged and the result
to know what the instruction is doing.
I intend to gradually replace all uses of the more complicated sequence/extract
with these (or single-element insert/extracts), and then remove the older
variants. For now we start with legalization.

r296565 attempted to add better diagnostics when an unordered container
is instantiated with a hash that doesn't meet the Hash requirements.
However I mistakenly checked the wrong set of requirements. Specifically
it checked if the hash met the requirements for specializations of
std::hash. However these requirements are stricter than the generic
Hash requirements.
This patch fixes the assertions to only check the Hash requirements.

The comments were wrong, and this is not an obvious transform.
This hopefully makes it clearer that we're missing the commuted
patterns for adds. It's less clear that this is actually a good
transform for all micro-arch.
This is prep work for trying to clean up the current adc/sbb
codegen because it's definitely not happening optimally.

In the DWARF 4 Spec section 7.2.2, data in many DWARF sections, and some DWARF structures start with "Initial Length Values", which are a 32-bit length, and an optional 64-bit length if the 32 bit value == UINT32_MAX.
This patch abstracts the Initial Length type in YAML, and extends its use to all the DWARF structures that are supported in the DWARFYAML code that have Initial Length values.

In an effort to move the various DataBuffer / DataExtractor
classes from Core -> Utility, we have to separate the low-level
functionality from the higher level functionality. Only a
few functions required anything other than reading/writing
raw bytes, so those functions are separated out into a
more appropriate area. Specifically, Dump() and DumpHexBytes()
are moved into free functions in Core/DumpDataExtractor.cpp,
and GetGNUEHPointer is moved into a static function in the
only file that it's referenced from.

This set may affect code generation and is sensitive to link order (and

Prior to MSVC 2015 we had to manually include this header any
time we were going to include <thread> or <future> due to a
bug in MSVC's STL implementation. This has been fixed in MSVC
for some time now, and we require VS 2015 minimum, so we can
remove this across all subprojects.

in clang and compiler-rt that feed multiple inputs to a
testing utility by globbing, all of which are either disabled
on Windows currently or using xargs / find hacks.

Summary:
If a loop contains a Phi node which has an invariant input from back
edge, it is profitable to peel such loops (rather than unroll them) to
use the advantage that this Phi is always invariant starting from 2nd
iteration. After the 1st iteration is peeled, other optimizations can
potentially simplify calculations with this invariant.

Summary:
In current implementation the loop peeling happens after trip-count based partial unrolling and may
sometimes not happen at all due to it (for example, if trip count is known, but UP.Partial = false). This
is generally bad, the more than there are some situations where peeling is profitable even if the partial
unrolling is disabled.
This patch is a NFC which reorders peeling and partial unrolling application and prepares the code for
implementation of the said optimizations.

pthread_self() returns a pthread_t, but we were setting it to
an int. It seems the cast to int when calling sysctl is still
the correct thing to do, though.

Doing so defines the type llvm::thread. On FreeBSD, we need
to call a macro which references its own ::thread type, which
causes an ambiguity due to ADL when inside of the llvm namespace.
Since we don't even need this unless LLVM_ENABLE_THREADS == 1,
we don't even need this type anyway, as it is always equal to
std::thread, so we can just use that directly.
