[EarlyCSE][OpaquePointers]Replace assert with return for mask type check.
When EarlyCSE tries to common vector masked loads/stores, it first checks that
they have same base operand and then assumes that this is enough for mask types
to be equal. This is true for typed pointers but false for opaque ones -
two loads of different vector sizes from same base pointer '%b' are the same,
`ptr %b`. (For typed pointers, `%b` was cast to vector pointer type so bases
Change assert to return from lambda `isSubmask` so this transformation properly
works with opaque pointers.
