fix regression with MEM commoning

This fixes a regression when canonicalizing refs for LIM PR84362.
This possibly unshares and rewrites the refs in the internal data
and thus pointer equality no longer works in ref_always_accessed
computation.

* tree-ssa-loop-im.c (ref_always_accessed::operator ()):
Just check whether the stmt stores.
