This patch implements atomic intrinsics atomic.load.add (sub,and,or,xor, nand), atomic.swap and atomic.cmp.swap, all in i8, i16 and i32 versions. The intrinsics are implemented by creating pseudo-instructions, which are then expanded in the method MipsTargetLowering::EmitInstrWithCustomInserter. Patch by Sasa Stankovic. llvm-svn: 132323

This patch implements atomic intrinsics atomic.load.add (sub,and,or,xor, nand), atomic.swap and atomic.cmp.swap, all in i8, i16 and i32 versions. The intrinsics are implemented by creating pseudo-instructions, which are then expanded in the method MipsTargetLowering::EmitInstrWithCustomInserter. Patch by Sasa Stankovic. llvm-svn: 132323

Set mayLoad or mayStore flags for SC and LL in order to prevent LICM from moving them out of the loop. Previously, stores and loads to a stack frame object were inserted to accomplish this. Remove the code that was needed to do this. Patch by Sasa Stankovic. llvm-svn: 135415
