Fix a miscompilation caused by a typo. When turning a adde with negative value into a sbc with a positive number, the immediate should be complemented, not negated. Also added a missing pattern for ARM codegen. rdar://12559385 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166613 91177308-0d34-0410-b5e6-96231b3b80d8
