  [MergeFunc] Fix comparison of constant expressions

Functions using different constant expressions were incorrectly
merged, because a lot of state was missing from the comparison,
including the opcode, the comparison predicate, the GEP element
type, as well as the inbounds, inrange and nowrap poison flags.
