// @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()
