c: Allow comparison of pointers to complete and incomplete types for C11 [PR95630]
As noted in bug 95630, C11 removed a restriction in C99 on comparing
pointers to compatible complete and incomplete types (this was one of
the changes in N1439, which was largely a terminological change to
make incomplete types a subset of object types rather than a different
kind of type). Implement that change by using pedwarn_c99 with
OPT_Wpedantic for this diagnostic.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.
