So maybe it should just call clear_bb_flags instead of doing the loop
itself? Ok if that works.

That doesn't generally work, it clears too many flags (it was appearantly
designed for RTL).

Or maybe it could be argued that more tree-specific flags ought to be in BB_FLAGS_TO_PRESERVE, or that it would make more sense to define a more specific BB_FLAGS_TO_KEEP.

So maybe just change the loop at the end of evrp, it clearly wants to clean up after itself so just make it do it reliably.
