[test] Use -passes=instcombine instead of -instcombine in lots of tests. NFC
Another step moving away from the deprecated syntax of specifying
pass pipeline in opt.

[instcombine] Fold overflow check using umulo to comparison
If we have a umul.with.overflow where the multiply result is not used and one of the operands is a constant, we can perform the overflow check cheaper with a comparison then by performing the multiply and extracting the overflow flag.
(Noticed when looking at the conditions SCEV emits for overflow checks.)

[test][instcombine] Add test cases for all x.with.overflow overflow checks
For each of the x.with.overflow variants, if only the overflow bit is consumed, we can generate a direct overflow comparison. This precommits tests for each of the variants and tries to cover interesting cornercases.
