Original change's description:
> Reland "[regexp] Call the regexp interpreter without CEntry overhead"

> This is a reland of d4d28b73cb

> Original change's description:
> > [regexp] Call the regexp interpreter without CEntry overhead
> >
> > Previously all RegExp calls went through Runtime_RegExpExec when --regexp-interpret-all was set.
> >
> > This CL avoids the runtime overhead by calling into the interpreter directly from the RegExpExec Builtin when the regular expression subject was already compiled to ByteCode (i.e. after the first call).
