  Changed paths:
    M llvm/lib/Target/SystemZ/SystemZRegisterInfo.cpp
    M llvm/test/CodeGen/SystemZ/frame-14.ll
    M llvm/test/CodeGen/SystemZ/frame-16.ll

  Log Message:
  -----------
  [SystemZ] Use LA instead of AGR in eliminateFrameIndex().

Since AGR clobbers CC it should not be used here.

Fixes https://bugs.llvm.org/show_bug.cgi?id=47736.
