This is to fix a bug when a target only support conditional faulting load, see test case hoist_store_without_cstore. Split `-simplifycfg-hoist-loads-stores-with-cond-faulting` into `-simplifycfg-hoist-loads-with-cond-faulting` and `-simplifycfg-hoist-stores-with-cond-faulting` to control conditional faulting load and store respectively.
