  [JSC] Add common thunk generation

Reviewed by Justin Michaud and Mark Lam.

Some of JIT thunks are frequently used even from main thread, and those are typically *always used* whenever JIT is enabled.
We should eagerly generate them and make the lookup super fast. This patch adds CommonJITThunkID and pre-generates common
thunks when initializing JITThunks.
