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).

// The preprocessor shouldn't warn about extensions within macro bodies that
// aren't expanded.
#define TY typeof
#define TY1 typeof(1)
// But we should warn here
TY1 x; // expected-warning {{extension}}
TY(1) x; // FIXME: And we should warn here
// Note: this warning intentionally doesn't trigger on keywords like
// __attribute; the standard allows implementation-defined extensions
// prefixed with "__".
// Current list of keywords this can trigger on:
// inline, restrict, asm, typeof, _asm
