After r297760, __isOSVersionAtLeast in compiler-rt loads the CoreFoundation
symbols at runtime. This means that `@available` will always fail when used in a
binary without a linked CoreFoundation.
This commit forces Clang to emit a reference to a CoreFoundation symbol when
`@available` is used to ensure that linking will fail when CoreFoundation isn't
linked with the build product.

that became supported after r297019
The commit r297019 expanded the performSelector ObjC method family heuristic
to ensure that -Wobjc-unsafe-perform-selector covers all performSelector
variations. However, this made the -Warc-performSelector-leaks too noisy, as
that warning produces mostly false positives since the selector is unknown.
This commit reverts the ObjC method family heuristics introduced in r297019.
This ensures that -Warc-performSelector-leaks isn't too noisy. The commit still
preserves the coverage of -Wobjc-unsafe-perform-selector.

Up until now, vpmovm2 instruction described its destination operand size
by the source operand size. This patch adds new pattern for the vpmovm2
instruction. The node describes new expansion of the destination (from
{128|256} to 512).

Summary:
We currently do a linear scan through all of the Alignments array entries anytime getAlignmentInfo is called. I noticed while profiling compile time on a -O2 opt run that this function can be called quite frequently and was showing about as about 1% of the time in callgrind.
This patch puts the Alignments array into a sorted order by type and then by bitwidth. We can then do a binary search. And use the sorted nature to handle the special cases for INTEGER_ALIGN. Some of this is modeled after the sorting/searching we do for pointers already.
This reduced the time spent in this routine by about 2/3 in the one compilation I was looking at.
We could maybe improve this more by using a DenseMap to cache the results, but just sorting was easy and didn't require extra data structure. And I think it made the integer handling simpler.

I honestly do not understand this part of code as it is too tangled.
What I'm trying now is to carefully disentangle it by transforming
code without changing meaining to see if I can improve overall
readability.

Summary:
This patch adopts the recent changes that renamed `set_exception(exception_pointer)` to `unhandled_exception()`.
Additionally `unhandled_exception()` is now required, and so an error is emitted when exceptions are enabled but the promise type does not provide the member.
When exceptions are disabled a warning is emitted instead of an error, The warning notes that the `unhandled_exception()` function is required when exceptions are enabled.

Summary:
This removes the 'remapTypeIndices' method on every TypeRecord class. My
original idea was that this would be the beginning of some kind of
generic entry point that would enumerate all of the TypeIndices inside
of a TypeRecord, so that we could write generic graph algorithms for
them without duplicating the knowledge of which fields are type index
fields everywhere. This never happened, and nothing else uses this
method. I need to change the API to deal with merging into IPI streams,
so let's move it into the file that uses it first.
