[arm load/store optimizer] When trying to merge a base update load/store, make sure the base register and would-be writeback register don't conflict for stores. This was already being done for loads. Unfortunately, it is rather difficult to create a test case for this issue. It was exposed in 450.soplex at LTO and requires unlucky register allocation. <rdar://13394908> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177874 91177308-0d34-0410-b5e6-96231b3b80d8
