Is this what you meant? make check-gcc RUNTESTFLAGS=guality.exp doesn't ICE
with it anymore with verify_flow_info (); at the beginning as well as end of
variable_tracking_main.
The notes are intentionally in between bbs, and it is assumed that the cfg
doesn't change after var-tracking pass, otherwise targets should disable
var-tracking at its standard spot and perform it at the end of machine reorg
pass (as e.g. ia64 and a few other targets do).
