[mips] Revert fixes for PR32020. The fix introduces segfaults and clobbers the value to be stored when the atomic sequence loops. Revert "[Target/MIPS] Kill dead code, no functional change intended." This reverts commit r296153. Revert "Recommit "[mips] Fix atomic compare and swap at O0."" This reverts commit r296134. llvm-svn: 297380
