annotate gen/optimizer.cpp @ 1486:9ed0695cb93c

Teach `-dgc2stack` to promote GC allocations in simple loops to stack allocations too. (A "simple" loop is one where the allocation isn't used in a subsequent iteration) This also means it's no longer necessary to run this pass multiple times. Running it once after inlining should now catch all cases.
