Headers: Define __INT64_TYPE__ in terms of getInt64Type(), which isn't always
'long'. The practical upshot is so that the uint64_t we define in our stdint.h
ends up being compatible with that defined by gcc (at least on Darwin), which
otherwise could lead to type incompatibilities with other system headers.
