which is should have done from the beginning. As usual, the most
fun with this sort of change is updating all the testcases.

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.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

pointers, by extending the "composite pointer type" logic to include
member pointer types.
Introduce test cases for member pointer comparisons, including those
that involve the builtin operator candidates implemented earlier.

in C++, taking into account conversions to the "composite pointer
type" so that we can compare, e.g., a pointer to a derived class to a
pointer to a base class.
Also, upgrade the "comparing distinct pointer types" from a warning to
an error for C++, since this is clearly an error. Turns out that we
hadn't gone through and audited this code for C++, ever.
