Bryan Chan 625f2dccd4 cmd/compile/internal/ssa: handle symbol address comparisons consistently
CL 38338 introduced SSA rules to optimize two types of pointer equality
tests: a pointer compared with itself, and comparison of addresses taken
of two symbols which may have the same base. This patch adds rules to
apply the same optimization to pointer inequality tests, which also ensures
that two pointers to zero-width types cannot be both equal and unequal
at the same time.

Fixes #24503.
