[Statepoint] Mark FixupStatepointCallerSaved as preserving the CFG

Authored by craig.topper on May 12 2020, 3:19 PM.



I can't find anything obvious in this pass that invalidates the CFG. So mark it as preserving so we stop rerunning some analysis passes.

I'm hoping this will restore some compile time lost by D75936 and D75937.
