[MachineLICM] Fix incorrect CSE on hoisted const load (#73007)
When hoisting an invariant load, we should not combine it with an
existing load through common subexpression elimination (CSE). This is
because there might be memory-changing instructions between the existing
load and the end of the block entering the loop.
