Douglas Gregor b8eaf2944b Audit uses of Sema::LookupSingleName for those lookups that are
intended for redeclarations, fixing those that need it. Fixes PR6831.

This uncovered an issue where the C++ type-specifier-seq parsing logic
would try to perform name lookup on an identifier after it already had
a type-specifier, which could also lead to spurious ambiguity errors
(as in PR6831, but with a different test case).

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

Douglas Gregor 104ee00181 Downgrade errors when trying to catch a pointer or reference to
incomplete type to warnings; GCC (and EDG in GCC compatibility mode)
permit such handles. Fixes PR6527.

(For real this time)

Chandler Carruth 3681e58d8b Revert r97925, it only contained the test updates not the actual fix.

Daniel Dunbar 8fbe78f6fc 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).
