[JSC] Implement CustomAccessor / CustomValue / Getter / Setter handlers
https://bugs.webkit.org/show_bug.cgi?id=275008
rdar://129088798
Reviewed by Justin Michaud.
This patch extends Handler IC to support CustomAccessor / CustomValue / Getter
/ Setter.
We simply add handler implementations for them. To clean up our implementations,
we introduce StaticScratchRegisterAllocator, which assigns scratch registers
at compile time. And we use it to define BaselineJITRegisters.
