KWIML: Make test_INT robust to #define-d int#_t and INT#_C 

Our TEST* macro calls pass arguments such as "int64_t" with the
expectation that the preprocessing token will be used literally.
Some platforms #define int64_t as "long long" which is not a valid
preprocessing token.  Perform preprocessor symbol concatenation
on the type names at the first level of macro evaluation to avoid
expanding the names.
