argument.  This avoids the argument from being silenced when the argument is
the NULL macro, which is defined in a system header.  This also makes the output
a bit nicer, e.g.:

t.c:8:3: warning: null passed to a callee which requires a non-null argument
  func1(NULL, cp2, i1);
  ^     ~~~~

vs something like:

t.c:8:10: warning: argument is null where non-null is required
  func1(NULL, cp2, i1);
        ^

1. When we accept "#garbage" in asm-with-cpp mode, change the token kind
   of the # to unknown so that the preprocessor won't try to process it as
   a real #.  This fixes a crash on the attached example
2. Fix macro definition extents processing to handle #foo at the end of a
   macro to say the definition ends with the foo, not the #.

This is a follow-on fix to r72283, and rdar://6916026

expressions. We are now missing template instantiation logic for only
three classes of expressions:
  - Blocks-related expressions (BlockExpr, BlockDeclRefExpr)
  - C++ default argument expressions
  - Objective-C expressions

Additionally, our handling of DeclRefExpr is still quite poor, since
it cannot handle references to many kinds of declarations.

As part of this change, converted the TemplateExprInstantiator to use
iteration through all of the expressions via clang/AST/StmtNodes.def,
ensuring that we don't forget to add template instantiation logic for
any new expression node kinds.

expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.

Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.

  (T(*)(int[x+y]));

is an (invalid) paren expression, but "x+y" will be parsed as part of the (rejected) type-id,
so unnecessary Action calls are made for an unused (and possibly leaked) "x+y".

Use a different scheme, similar to parsing inline methods. The parenthesized tokens are cached,
the context that follows is determined (possibly by parsing a cast-expression),
and then we re-introduce the cached tokens into the token stream and parse them appropriately.

The TokenLexer may encounter annotations if the parser enters them using Preprocessor::EnterTokenStream.
So check for annotation before using the Token's IdentifierInfo.

Handle correctly a very ugly part of the C++ syntax. We cannot disambiguate between a parenthesized type-id and
a paren expression without considering the context past the parentheses.

Behold:
