description:
lint: use macro for encoding type information

In lint's strict bool mode, initialization must be of the correct type.
This affects the bool fields in ttab_t, which are initialized with int.
To keep the code brief, preserve these ints and let a macro do the
actual work of converting them to bool.

No change to the generated binary.
