gcc14-bitint-wip.patch

Updated patch.  This can already do some simple lowering of the large/huge
_BitInt operations, like:
void
foo (_BitInt(192) *x, _BitInt(192) *y, _BitInt(135) *z, _BitInt(135) *w)
{
  x[0] &=3D y[0];
  x[1] |=3D y[1];
  x[2] ^=3D y[2];
  x[3] =3D ~y[3];
  z[0] &=3D w[0];
  z[1] |=3D w[1];
  z[2] ^=3D w[2];
  z[3] =3D ~w[3];
}

_BitInt(517) a, b, c, d, e, f;

void
bar (void)
{
  a &=3D b;
  c |=3D b;
  d ^=3D b;
  e =3D ~f;
}

Additions/subtractions/left shift by small constant next.=
