ifcombine makes
optimizing two comparisons to _13
Merging blocks 3 and 4
to
[local count: 955630225]:
d_10 = (short unsigned int) a.3_5;
_9 = a.3_5 & 65535;
_2 = d_10 != 0;
_1 = _9 == 0;
_13

I wonder if we should just do this:
(for neeq (ne eq)
(simplify
(neeq (convert:s @0) integer_zerop@1)
(with
{
tree inside_type = TREE_TYPE (@0);
tree outer_type = TREE_TYPE (@1);
}

Note this does not get optimized at the rtl level on all targets either, e.g.
aarch64 we get:
tst w0, 65535
and w0, w0, 65535
ccmpw0, 0, 4, eq
beq .L3
