ExpectAndConsume instead of custom diag logic.  This gets us an
insertion hint and positions the ; at the end of the line 
instead of on the next token.  Before:

t.c:5:1: error: expected ';' after return statement
}
^

after:

t.c:4:11: error: expected ';' after return statement
  return 4

builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).

I'm not completely sure this is the right way to fix this issue, but it seems 
reasonable, and it's consistent with the non-template code for this 
construct.

specialization's arguments are identical to the implicit template
arguments of the primary template. Typically, this is meant to be a
declaration/definition of the primary template, so we give that
advice.

argument deduction failed. For example, given

  template<typename T> struct is_same<T, T> { ... };

template argument deduction will fail for is_same<int, float>, and now
reports enough information

Right now, we don't do anything with this extra information, but it
can be used for informative diagnostics that say, e.g., "template
argument deduction failed because T was deduced to 'int' in one
context and 'float' in another".

It's an error to use a function declared in a class definition as a default argument before the function has been declared.
