[JSC] Simplify JSFunction creation operation
https://bugs.webkit.org/show_bug.cgi?id=276602
rdar://131740938
Reviewed by Justin Michaud.
JSFunction creation is taking cost because it is accessing usually unused
memory, UnlinkedFunctionExecutable.
But we do not need to touch these memory actually since this is only necessary
to identify structure, and which
can be computed when compiling JIT code. We add bunch of operations for
specific structures and JIT compiler
use one of them so that we do not need to read memory from
UnlinkedFunctionExecutable at runtime.
