Quick: Clean up optimization pass order.
Move the TypeInference pass to post-opt passes and make it
a PassMEMirSsaRep as we need to rerun the pass if the SSA
representation has changed. (Though we currently don't have
any pass that would require it.)
The results of MethodUseCount and ConstantPropagation passes
are used only in the BBOptimization and codegen and stay
valid across BBOptimization and SuspendCheckElimination, so
move them out of post-opt passes to just before the BBOpt
(and reverse the dependency between ConstantPropagation and
init reg locations passes).
