[X86] Don't preserve Win64 SSE CSRs when SSE is disabled Code that doesn't use floating point and doesn't use SSE (kernel code) shouldn't save and restore SSE registers. Fixes PR30503 llvm-svn: 282819

[AArch64] Extend CallingConv::X86_64_Win64 to AArch64 as well Rename the enum value from X86_64_Win64 to plain Win64. The symbol exposed in the textual IR is changed from 'x86_64_win64cc' to 'win64cc', but the numeric value is kept, keeping support for old bitcode.
