This first step just adds definitions for SLLK, SRLK and SRAK. The next patch will actually make use of them during codegen. insn-bad.s tests that some form of error is reported when using these instructions on z10. More work is needed to get the "instruction requires: distinct-ops" that we'd ideally like, so I've stubbed that part out for now. I'll come back and make it mandatory once the necessary changes are in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186680 91177308-0d34-0410-b5e6-96231b3b80d8
