CodeGen: support SwiftError SwiftCC on Windows x64 Add support for passing SwiftError through a register on the Windows x64 calling convention. This allows the use of swifterror attributes on parameters which is used by the swift front end for the `Error` parameter. This partially enables building the swift standard library for Windows x86_64. llvm-svn: 313791

X86: remove R12 from CSR on Windows x64 SwiftCC R12 is used for the SwiftError parameter. It is no longer a CSR as it is used for transfer the SwiftError, and the caller must preserve it if they need to. llvm-svn: 314165
