We were not aligning the code size,
so read-only data, which follows in the same
segment, could be arbitrarily misaligned.

Avoids global array buffer overflows if they are
indexed using some of the values between NTYPE
and NALLTYPE.  It is entirely likely that not all of these
are necessary, but this is the C compiler and not worth
worrying much about.  This change takes up only a
few more bytes of memory and makes the behavior
deterministic.

Alternatively, we could expand the ewidth array
in [568]c/txt.c to have NALLTYPES elements and
give all types above NTYPE a width of -1.

I don't think it's worth it since TDOT and TOLD
are the only two type values above NTYPE that
are passed to typ:

$ /tmp/cctypes
cc/dcl.c:683: 			t->down = typ(TOLD, T);
cc/dcl.c:919: 		return typ(TDOT, T);
$

variant of IMUL, I couldn't make 6l able to differentiate it without
huge changes, so I called it IMUL3.
