Refactor CONSTANTP a bit more.
- Non-constant special forms don't fall into CONSTANT-FUNCTION-CALL-P.
It rightly got NIL either way, but avoiding a useless test
gives a measurable performance improvement.
- Malformed special forms always cause CONSTANTP to return NIL
to match the behavior of at least 4 other Lisp implementations.
- UNWIND-PROTECT and M-V-PROG1 handlers do not cons.
- cold-init functions are not needed.
