Keno Fischer 99ca52276f [LAA] Prevent invalid IR for loop-invariant bound in loop body ...

Summary:
If LAA expands a bound that is loop invariant, but not hoisted out
of the loop body, it used to use that value anyway, causing a
non-domination error, because the memcheck block is of course not
dominated by the scalar loop body. Detect this situation and expand
the SCEV expression instead.
