Make more use of GET_MODE_UNIT_PRECISION
This patch is like the earlier GET_MODE_UNIT_SIZE one,
but for precisions rather than sizes. There is one behavioural
change in expand_debug_expr: we shouldn't use lowpart subregs
for non-scalar truncations, since that would just reinterpret
some of the scalars and drop the rest. (This probably doesn't
trigger in practice.) Using TRUNCATE is fine for scalars,
since simplify_gen_unary knows when a subreg can be used.
