Please take the time to read through the gcc manual thoroughly.
This will tell you, among other things you will probably need
later, about TRULY_NOOP_TRUNCATION, MODES_TIEABLE_P and named
patterns, like movqi, {zero_,}extendqi[hsdt]i and trunc[tdsh]iqi.
If you haven't used up PSImode and PHImode yet, you could also
promote characters to one of these modes, thus allowing bool
to use the lower 8 bits.
