[MachineLICM] Allow hoisting loads from invariant address (#70796)
Sometimes, loads can appear in a loop after the LICM pass is executed
the final time. For example, ExpandMemCmp pass creates loads in a loop,
and one of the operands may be an invariant address.
This patch extends the pre-regalloc stage MachineLICM by allowing to
hoist invariant loads from loops that don't have any stores or calls
and allows load reorderings.
