ARM: Optimize div/rem when dividend is compared with a non-negative
When a divisor is a positive constant and a dividend is compared with a
non-negative value, the result of the comparison can guarantee that the
dividend is non-negative. In such a case there is no need to generate
instructions correcting the result of div/rem.
The CL implements this optimization for ARM32/ARM64.
