Clang does not accept `-x objective-c` with WebAssembly target and it
crashes with "Objective-C support is unimplemented for object file
format" for now. `-enable-objc-interop` can work without the objc
runtime support (which is indicated by `objc_interop` feature), so this
adds a new `objc_codegen` feature to require Objective-C support only
at compile-time.
Commit the platform definition and build script work necessary to
cross-compile for arm64_32.
arm64_32 is a variant of AARCH64 that supports an ILP32 architecture.
Introduce and use the new `%target-abi` and `%target-import-type`
subsitutions in the IRGen tests. The former allows us to differentiate
between the Windows and SysV ABI differences and the latter for the
indirected import semantics required by PE/COFF. This makes all the
IRGen tests succeed on Windows.
Update the IRGen tests for Windows IRGen. This is an improvement over
what we have currently, but is not sufficient to get all the IRGen tests
passing yet.
Avoid a temporary file and executing FileCheck multiple types and prefer
multiple check prefixes and streaming. Additionally, enable some of
previously XFAIL'ed tests on Linux as well as tests that were marked as
requiring Objective-C interop.
Use the generic type lowering algorithm described in
"docs/CallingConvention.rst#physical-lowering" to map from IRGen's explosion
type to the type expected by the ABI.
Change IRGen to use the swift calling convention (swiftcc) for native swift
functions.
Use the 'swiftself' attribute on self parameters and for closures contexts.
Use the 'swifterror' parameter for swift error parameters.
Change functions in the runtime that are called as native swift functions to use
the swift calling convention.

This patch adds powerpc64le Linux support. While the patch also adds
the matching powerpc64 bits, there are endian issues that need to be
sorted out.
The PowerPC LLVM changes for the swift ABI (eg returning three element
non-homogeneous aggregates) are still in the works, but a simple LLVM
fix to allow those aggregates results in swift passing all but 8
test cases.
