frame index. eliminateFrameIndex will replace these instructions with (LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use. This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame pointer elimination. However since they were marked as implicitly using SP they could not be rematerialised. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62238 91177308-0d34-0410-b5e6-96231b3b80d8
