The fix for
https://bugs.webkit.org/show_bug.cgi?id=147461
eliminated rdi as regT5 on X86-64 Windows. rcx became the new regT5 for Windows X86-64, but that is also argumentGPR0. The only use of regT5 is arityFixupGenerator() which also requires that regT5 doesn't collide with various register, including argumentGPR0.
