Richard Smith db70052b65 Remove bogus check for template specialization from self-comparison warning.
The important check is that we're not within a template *instantiation*, which
we check separately.

Richard Smith 07c0f285ba Fix a couple of wrong self-comparison diagnostics.
Check whether we are comparing the same entity, not merely the same
declaration, and don't assume that weak declarations resolve to distinct
entities.

Eli Friedman 5a722e92af Add self-comparison warnings for fields.
This expands very slightly what -Wtautological-compare considers to be
tautological to include implicit accesses to C++ fields and ObjC ivars.
I don't want to turn this into a full expression-identity check, but
these additions seem pretty well-contained, and maintain the theme
of checking for "x == x".
