target/mips: Explode MO_TExx -> MO_TE | MO_xx

Extract the implicit MO_TE definition in order to replace
it by runtime variable in the next commit.

Mechanical change using:

  $ for n in UW UL UQ UO SW SL SQ; do \
      sed -i -e "s/MO_TE$n/MO_TE | MO_$n/" \
           $(git grep -l MO_TE$n target/mips); \
    done

manually remove superfluous parenthesis in nanoMIPS gen_save().
