  [Pipelines] Add a test how DCE works after ArgumentPromotion

The ArgumentPromotion pass uses Mem2Reg promotion at the end to cutting
down generated alloca instructions as well as meaningless stores and
this behavior can leave unused (dead) arguments.

The test shows that the arguments are not removed in the current
optimization pipeline.
