  -----------
  AMDGPU: Remove xnack and sramecc subtarget features

Now that these are controlled by module flags, the subtarget
features were just used for assembler and disassembler controls.
Now that the assembler and disassembler can infer these from
the e_flags and target directives, they are no longer necessary.
