  AMDGPU: Remove attempt at simplifying the format string in printf lowering

This avoids computing the dominator tree by removing the
simplifyInstruction use.

This was applying simplification with some kind of questionable
load-store forwarding and looking for the global. This had to have
been an ancient hack copied from previous backends. In the OpenCL
case, this is always emitted as required the direct global reference
anyway.
