/	Epilogues for calling functions w/ Microsoft x64 convention.
/
/	@param	%rax is address of windows x64 function to call
/	@param	%rsi is ignored
/	@param	%rdx,%rcx,%r8,%r9,stack are params (unlimited)
/	@param	%xmm0,%xmm1,%xmm2 are double params (limited to 3)
/	@return	is in %rax, %xmm0, or %st
/	@note	GCC 4.8+ and Clang can avoid this indirection
/	@note	thunk that jumps here must setup frame
/	@note	this is so much faster than __nt2sysv()
