Chandler Carruth 13b21be065 Factor out (some of) the checking for invalid forms of pointer
arithmetic into a couple of common routines. Use these to make the
messages more consistent in the various contexts, especially in terms of
consistently diagnosing binary operators with invalid types on both the
left- and right-hand side. Also, improve the grammar and wording of the
messages some, handling both two pointers and two (different) types.

The wording of function pointer arithmetic diagnostics still strikes me
as poorly phrased, and I worry this makes them slightly more awkward if
more consistent. I'm hoping to fix that with a follow-on patch and test
case that will also make them more helpful when a typedef or template
type parameter makes the type completely opaque.

Suggestions on better wording are very welcome, thanks to Richard Smith
for some initial help on that front.

Daniel Dunbar a5728872c7 Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- 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).

Daniel Dunbar d7d5f0223b Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Eli Friedman f1c7b48638 Make sure to take the unqualified versions of the canonical types for
type-checking pointer subtraction; if the canonical types aren't used,
the qualifiers won't always get stripped off correctly.
