Keith Randall 83a33d3855 cmd/compile: reverse order of slice bounds checks
Turns out this makes the fix for 28797 unnecessary, because this order
ensures that the RHS of IsSliceInBounds ops are always nonnegative.

The real reason for this change is that it also makes dealing with
<0 values easier for reporting values in bounds check panics (issue #30116).

Makes cmd/go negligibly smaller.

Update #28797
