fix size corruption when simplifing 'x != 0' to 'x'
In commit d329775c2 ("simplify 'x != 0' or 'x == 1' to 'x'")
the comparison was optimized away if the operand's size == 1
but this is only valid if the comparison also has a size == 1.
Fix this by restricting this optimization only when both
the comparison instruction and its operand has a size == 1.
Fixes: d329775c2 ("simplify 'x != 0' or 'x == 1' to 'x'")
