[DSE] Move legacy tests to DeadStoreElimination/MemDepAnalysis.

Browse Source 
This patch moves the tests for the old MemDepAnalysis based DSE
implementation to the MemDepAnalysis subdirectory and updates them to
pass -enable-dse-memoryssa=false.

This is in preparation for the switch to MemorySSA-backed DSE.
