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. llvm-svn: 348454

[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.
