Extended Description

Consider:
long foo(long a, long b, long v1, long v2) {
if (a >= v1 && a < v2)
return b;
return 0;
}

We generate:
cmp x0, x2
csinc w8, wzr, wzr, lt
cmp x0, x3
csinc w9, wzr, wzr, ge
and w8, w8, w9
cmp w8, #​0
csel x0, x1, xzr, ne
ret

This seems like it should have generated something like:
mov x4, #​0
cmp x0, x2
ccmp x0, x3, #imm, lt
csel x0, x1, x4, ge
ret
