[PATCH] D18952: [SystemZ] Add SVC instruction.

[Ulrich Weigand via llvm-commits]

uweigand added a comment.

While this is not for CodeGen, I think for the benefit of analysis tools (e.g. LLDB) the pattern should still be marked with the appropriate flags, at least something like "isCall = 1, Defs = [CC]".  Not sure if hasSideEffects is necessary, but it probably cannot hurt to add it as well.

Otherweise the patch looks good.
