Alexander Markov 736cec66d9 [vm/compiler] Avoid unmatched representations after the last SelectRepresentations pass ...

Before this fix, Canonicalize pass could change representation
of inputs of EqualityCompare after the last SelectRepresentations
pass. This results in unmatched representations and invalid code
generated.

The fix is to disallow canonicalization of EqualityCompare
from null-aware to non-null-aware after the last SelectRepresentations.
