are expanded from macros (and if so, omit the warning). Previously we were just looking at the
location of the binary expression.
Fixes <rdar://problem/8435950>.

around by exempting enums from the check, but this doesn't handle a lot of
cases. A better approach is to directly check if the operator comes from
a macro expansion.
I've removed a reference to the rdar that originally led to the enum
suppression when removing it's overly contrived test case. Let me know if that
number or a more reasilistic test case involving enums is still needed.

unevaluated contexts, because they only matter for code that will
actually be evaluated at runtime.
As part of this, I had to extend PartialDiagnostic to support fix-it
hints.

- 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).

"x == x" and "x != x". We emit a warning for these since they always evaluate
to a constant value and often indicate a logical error.
Added test case for this check.
