When computing the composite pointer type for relational comparisons,
equality comparisons, and conditional operators, produce a composite
pointer type with the appropriate additional "const" qualifiers if the
pointer types would otherwise be incompatible. This is a small
extension (also present in GCC and EDG in a slightly different form)
that permits code like:
void** i; void const** j;
i == j;
with the following extwarn:
t.cpp:5:5: warning: comparison of distinct pointer types ('void **' and
'void const **') uses non-standard composite pointer type
'void const *const *' [-pedantic]
i == j;

Fixes PR6346, and I'll be filing a core issue about this with the C++
committee.
