MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement a
temporary workaround for matching inc/dec on x86_64 to the correct instruction. - This hack will eventually be replaced with a robust mechanism for handling matching instructions based on the available target features. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98858 91177308-0d34-0410-b5e6-96231b3b80d8
