[SystemZ] Add CodeGen test cases This adds all CodeGen tests for the SystemZ target. This version of the patch incorporates feedback from a review by Sean Silva. Thanks to all reviewers! Patch by Richard Sandiford. llvm-svn: 181204

; Test 16-bit atomic exchange.

; RUN: llc < %s -mtriple=s390x-linux-gnu | FileCheck %s -check-prefix=CHECK
; RUN: llc < %s -mtriple=s390x-linux-gnu | FileCheck %s -check-prefix=CHECK-SHIFT
; Check exchange with a variable.
; - CHECK is for the main loop.
; - CHECK-SHIFT makes sure that the negated shift count used by the second
; RLL is set up correctly. The negation is independent of the NILL and L
; tested in CHECK. CHECK-SHIFT also checks that %r3 is not modified before
; being used in the RISBG (in contrast to things like atomic addition,
; which shift %r3 left so that %b is at the high end of the word).

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.

[SystemZ] Use zeroing form of RISBG for some AND sequences RISBG can handle some ANDs for which no AND IMMEDIATE exists. It also acts as a three-operand AND for some cases where an AND IMMEDIATE could be used instead. It might be worth adding a pass to replace RISBG with AND IMMEDIATE in cases where the register operands end up being the same and where AND IMMEDIATE is smaller. llvm-svn: 186072
