Baseline JIT and DFG IC code generation should be unified and rationalized
https://bugs.webkit.org/show_bug.cgi?id=122939

Reviewed by Geoffrey Garen.

Introduce the JITInlineCacheGenerator, which takes a CodeBlock and a CodeOrigin plus
some register info and creates JIT inline caches for you. Used this to even furhter
unify the baseline and DFG ICs. In the future we can use this for FTL ICs. And my hope
is that we'll be able to use it for cascading ICs: an IC for some instruction may realize
that it needs to do the equivalent of get_by_id, so with this generator it will be able
to create an IC even though it wasn't associated with a get_by_id bytecode instruction.
