[cmucl-imp] Frame size for local calls

The comment for the ALLOCATE-FRAME vop reads: This is emitted directly before either a known-call-local, call-local, or a multiple-call-local. All it does is allocate stack space for the callee (who has the same size stack as us). Does that mean that all local calls in a component use the same frame size? Isn't that wasteful? Helmut
