In the below scenario, we must be able to skip the a DBG_VALUE instruction and
remove the dead store.
%vreg0<def> = L2_loadri_io <fi#15>, 0; mem:LD4[%dataF](align=4)
DBG_VALUE %vreg0, %noreg, !"dataF", <!184>; IntRegs:%vreg0
S2_storeri_io <fi#15>, 0, %vreg0; mem:ST4[%dataF]
In reality, this kind of stores are eliminated before Stack Slot Coloring pass,
possibly in instruction lowering
