Varun Gandhi 92dcb1d2db [Clang] Introduce Swift async calling convention.
This change is intended as initial setup. The plan is to add
more semantic checks later. I plan to update the documentation
as more semantic checks are added (instead of documenting the
details up front). Most of the code closely mirrors that for
the Swift calling convention. Three places are marked as
[FIXME: swiftasynccc]; those will be addressed once the
corresponding convention is introduced in LLVM.

Saleem Abdulrasool f587857c88 ARM, AArch64: support `__attribute__((__swiftcall__))`
Support the Swift calling convention on Windows ARM and AArch64.  Both
of these conform to the AAPCS, AAPCS64 calling convention, and LLVM has
been adjusted to account for the register usage.  Ensure that the
frontend passes this into the backend.  This allows the swift runtime to
be built for Windows.
