Why before pass_build_ssa? (version 4.1.1)
It depends on the properties your pass requires. If you ask for
PROP_cfg and PROP_gimple_any then you should schedule it after the CFG
has been built, but if you need PROP_ssa, then you must be after
pass_build_ssa which implies that your pass only gets enabled at -O1+.
