Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally. No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way. llvm-svn: 125747

Target/X86: Never use the redzone for Win64 ABI functions. Summary: Until now, we did this (among other things) based on whether or not the target was Windows. This is clearly wrong, not just for Win64 ABI functions on non-Windows, but for System V ABI functions on Windows, too. In this change, we make this decision based on the ABI the calling convention specifies instead.

Target/X86: Tweak allocating shadow area (aka home) on Win64. It must be enough for caller to allocate one. llvm-svn: 124949
