Sentence-case bug type, and pull tests from region-only-test.c into misc-ps-region.store.m (removing an extra unneeded test file).  Also add a bunch of FIXME comments for future enhancements.

  * If the unsigned type is smaller than the signed type, never warn, because
    its value will not change when zero-extended to the larger type.
  * If we're testing for (in)equality, and the unsigned value is an integer
    constant whose sign bit is not set, never warn, because even though the
    signed value might change, it can't affect the result of the equality.

Also make the comparison test cases much more rigorous, and have them expose
the subtle differences between C and C++ here.

where get_origin is actually a function and the user has forgotten the
parentheses. Instead of giving a lame note for the fix-it, give a
full-fledge error, early, then build the call expression to try to
recover.

If a member variable of reference type is bound to a temporary in its member initializer it needs to be destroyed at the end of the constructor.

conversions, because we may end up binding a reference to a function
or array.

Make sure that EnumConstantDecls always get a type, even when they have type-dependent initializers.

Make ASTContext::getIntWidth return 1 for all boolean type variations, not just for the unqualified, unaliased bool.

Be a little more careful when trying to extract a TypeDecl from a enum/class/struct/union specifier; in invalid code, we may also see ClassTemplateDecls.

When collecting types for built-in candidates, make arrays decay to pointers. Otherwise, subscripting an array leads to no candidates at all. Fixes PR5360.

(without complaining if it fails) to get proper semantics: reference
binding with a derived-to-base conversion and the enumeration of
constructors for user-defined conversions. There are probably more
cases to fix, but my prior attempt at statically ensuring that
complete-type checking always happens failed. Perhaps I'll try again.

With this change, Clang can parse include/llvm/*.h!

DiagnoseSignCompare into Sema::CheckSignCompare and call it from more places.

Add some enumerator tests.  These seem to expose some oddities in the
types we're converting C++ enumerators to;  in particular, they're converting
to unsigned before int, which seems to contradict 4.5 [conv.prom] p2.
