Shall the workaround for llvm.12833 be removed?

[Chandlerooo]

I notice a workaround for llvm.12833:
https://github.com/ValveSoftware/steamos_mesa/blob/4d8013e2b0914bfb0472778ebf15e27faa0d39fb/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp

  /*
  * Workaround http://llvm.org/bugs/show_bug.cgi?id=12833
  */
 StringRef MArch = "";
 StringRef MCPU = "";
 Triple TT(unwrap(M)->getTargetTriple());
 JIT = builder.create(builder.selectTarget(TT, MArch, MCPU, MAttrs));

This compiler bug is already fixed: https://bugs.llvm.org/show_bug.cgi?id=12833
Shall this workaround be removed?
