Add callOperation to Baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=122306

Reviewed by Geoffrey Garen.

Created baseline JIT compatible versions for a few flavors of callOperation().
Migrated cti_op_new_regexp() and its caller to callOperation(operationNewRegexp()).

* dfg/DFGOperations.cpp: Moved operationNewRegexp() to JITOperations
* dfg/DFGOperations.h:
* jit/JIT.h:
(JSC::JIT::appendCall):
* jit/JITInlines.h:
