  Log Message:
  -----------
  [X86][AMX] Don't emit tilerelease for old AMX instrisic.

We should avoid mixing old AMX instrinsic with new AMX intrinsic. For
old AMX intrinsic, user is responsible for invoking tile release. This
patch is to check if there is any tile config generated by compiler. If
so it emit tilerelease instruction, otherwise it don't emit the
instruction.
