[Bug c/16332] New: feature request: x86-64 windows calling convention

["thutt at vmware dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The gcc x86-64 ABI uses esi/edi/edx/ecx/r8/r9 for the first six parameters.
Windows uses only 4 registers (edx/ecx,r8/r9).  

It would be very helpful for writing assembly code which runs on both Windows
and Linux to have a calling convention in x86-64 which is the same as the
Windows x86-64 __stdcall.
