This abstracts creation of ACALL Progs into package gc. The main benefit of this today is we can refactor away a lot of common boilerplate code. Later, once liveness analysis happens on the SSA graph, this will also provide an easy insertion point for emitting the PCDATA Progs immediately before call instructions. Passes toolstash-check -all.
