[JSC] Do not use ScratchRegisterAllocator in Handler IC
https://bugs.webkit.org/show_bug.cgi?id=275967
rdar://130702031
Reviewed by Justin Michaud.
This patch integrates fallback of AccessCase::Transition allocation slow path
via C function call so that
we do not need to use ScratchRegisterAllocator in handler implementation
anymore. This makes handler implementation
and error handling much simpler.
