Given 'typename T typename U', we would correctly diagnose the missing
comma, but incorrectly disambiguate the first parameter as being a
non-type parameter and complain that the 'T' is not a qualified-id.

The standard correctly forbids various decl-specifiers that dont make sense on non-type template parameters - such as the extern in:
template<extern int> struct X;
This patch implements those restrictions (in a fashion similar to the corresponding checks on function parameters within ActOnParamDeclarator).
Credit goes to miyuki (Mikhail Maltsev) for drawing attention to this issue, authoring the initial versions of this patch, and supporting the effort to re-engineer it slightly. Thank you!

- 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).
