BITINT_TYPE support to godump.cc, as I have no idea what you want to do in go
for that.
Example of problematic declaration in some header (so far on x86-64) would be
extern _BitInt(157) foo (unsigned _BitInt(384) x, signed _BitInt(15) y, int z);

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note, there is no guarantee that _BitInt(32) or _BitInt(64) are
passed/returned/laid out exactly like int32_t or int64_t (ditto for 8 and 16
bits), but on the current single target which supports them it is so far the
case.  _BitInt(128) has different alignment from __int128 though.
