Chris Lattner bb53efb016 fix rdar://7985267 - Don't emit an error about a non-pod argument
passed to va_start, it doesn't actually pass it.

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.

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).

Douglas Gregor fab31f47b2 When certain diagnostics involving run-time behavior would be emitted
in a potentially potentially evaluated context, queue those
diagnostics and only emit them if the context ends up being
potentially evaluated. This completes the fix for PR5761.

Douglas Gregor 7ca84af48e Suppress warnings and errors about certain uses of non-POD types (in
__builtin_offsetof, passing through an ellipsis) when we're in an
unevaluated context. This is the first part of the fix to PR5761,
which deals with the simple case of an unevaluated context.

Chris Lattner 56caf31afb Give the "cannot pass object of non-POD type 'class C' through variadic constructor; call will abort at runtime" warning a -W flag (non-pod-varargs) and default it being an error by default. There is no good reason to allow users to get bitten by this sort of thing by default.

Daniel Dunbar 8b57697954 Eliminate &&s in tests.
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Anders Carlsson 6816affaa4 Handle variadic constructors better. Share code between BuildCXXConstructExpr and BuildCXXTemporaryObjectExpr.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Anders Carlsson a7d069d63c Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.
