This change stops tracking assistG across malloc to reduce number of
slots the compiler must keep track of in mallocgc, which adds to
register pressure. It also makes the call to deductAssistCredit only
happen if the GC is running.
This is a microoptimization that on its own changes very little, but
together with other optimizations and a breaking up of the various
malloc paths will matter all together ("death by a thousand cuts").
