This patch adds function summaries, so that we don't need to recompute
various properties about function parameters/return values at each
callsite of a function. It also adds many interprocedural tests for
CFLAA.

The BSWAP of vector types is quite efficiently implemented using vector shuffles on SSE/AVX targets, we should reflect the typical cost of this to encourage vectorization.

Fix for PR27726 - sitofp i64 to fp128 was loading the merged load i64 to a x87 register preventing legalization for conversion to fp128.
Added 32-bit tests for fp128 cast/conversions.

Darwin added support in its Xcode 8.0 tools (released in the beta) for universal
files where offsets and sizes for the objects are 64-bits to allow support for
objects contained in universal files to be larger then 4gb. The change is very
straight forward. There is a new magic number that differs by one bit, much
like the 64-bit Mach-O files. Then there is a new structure that follow the
fat_header that has the same layout but with the offset and size fields using
64-bit values instead of 32-bit values.

There is a known intended race here. This is a follow-up to r264805,
which disabled tsan instrumentation for updates to instrprof counters.

Summary: Inliner needs ACT when calling InlineFunction. Instead of nullptr, we need to pass it in from SampleProfileLoader

We recently made MemorySSA own the walker it creates. As a part of this,
the MSSA test fixture was changed to have a `Walker*` instead of a
`unique_ptr<Walker>`. So, we no longer need to do `&*Walker` in order to
get a `Walker*`.

Specific instances of intrinsic calls may want to be convergent, such
as certain register reads but the intrinsic declaration is not.

The implicit operand is added by the initial instruction construction,
so this was adding an additional vcc use. The original one
was missing the undef flag the original condition had,
so the verifier would complain.

This will help sneak undefs past GVN into the DAG for
some tests.
Also add missing intrinsic for rsq_legacy, even though the node
was already selected to the instruction. Also start passing
the debug location to intrinsic errors.

Trying to expand short names with a relative path doesn't work, so this
first gets the module name to get a full path (which can still have short
names).

TargetLowering and DAGToDAG are used to combine ADDC, ADDE and UMLAL
dags into UMAAL. Selection is split into the two phases because it
is easier to match the two patterns at those different times.

After a store has been eliminated, when making sure that the
instruction iterator points to a valid instruction, dbg intrinsics are
now ignored as a new instruction.
