So, e.g. in the gcc.target/i386/sse4_1-pr88547-1.c testcase, we have before
veclower21:
v2di f13 (v2di x, v2di y)
{
vector(2) _1;
v2di _4;
[local count: 1073741824]:
_1 = x_2(D) <= y_3(D);
_4

Im slightly confused here, on entry to BB 5 we know the opposite of _1 < 0.0
no? if we branch to BB 5 we know !(_1 < 0.0) so we can't fold _1 <= 1.0, we
just know that the range of _1 is >= 0.0

There's similar issues with GIMPLE uses of last_stmt () which generally (but
not always) want to look at a possible control transfer stmt. It looks like

For delete_trivially_dead_insns we have
for (insn = get_last_insn (); insn; insn = prev)
{
int live_insn = 0;
prev = PREV_INSN (insn);
if (!INSN_P (insn))
continue;
