I think the PrintingPolicy may not be necessary because it's only used for
getting the name of the current TypeSpecType. More specifically, for just
differentiating vetween "bool" and "_Bool" for `TST_bool`. It also seems that
other setters that don't touch TypeSpecType use PrintingPolicy, like
`SetTypeSpecComplex` or `SetTypeSpecSign`

How so? I have tests under `test/Frontend/fixed_point_errors.c` that check for
an error thrown if `_Sat` is used with non-fixed point types.
