[JSC] Support fast C++ -> JS calls in x64
https://bugs.webkit.org/show_bug.cgi?id=309926
rdar://172519516
Reviewed by Sosuke Suzuki.
Implement vmEntryToJavaScriptWith0Arguments - vmEntryToJavaScriptWith6Arguments
variants in x64 too. It is not super hard: t0 (rax) is not used for
argument registers, so we can easily use it for scratch register.
