[PowerPC] Sign extend sub-word values for atomic comparisons Atomic comparison instructions use the sub-word load instruction on Power8 and up but the value is not sign extended prior to the signed word compare instruction. This patch adds that sign extension. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@282182 91177308-0d34-0410-b5e6-96231b3b80d8
