Find a builtin type according to a code such as `ull' or `ld'.
E.g P99_BUILTIN_TYPE(ull) should expand to unsigned long long. The complete list for the 35 builtin types (+ required typedefs):
| code | type | is signed | signed | unsigned | integer rank |
| b | _Bool | 0 | | b | 0 |
| c | char | | hh | uhh | 1 |
| d | double | | | | |
| dc | double _Complex | | | | |
| f | float | | | | |
| fc | float _Complex | | | | |
| i128 | int_least128_t | | | | |
| i16 | int_least16_t | | | | |
| i32 | int_least32_t | | | | |
| i64 | int_least64_t | | | | |
| i8 | int_least8_t | | | | |
| j | intmax_t | | | | |
| ld | long double | | | | |
| ldc | long double _Complex | | | | |
| t | ptrdiff_t | | | | |
| signed | 1 | i | u | 3 |
| hh | signed char | 1 | hh | uhh | 1 |
| l | signed long | 1 | l | ul | 4 |
