/* Here detect when we can distribute the truncation down past some
arithmetic. For example, if adding two longs and converting to an
int, we can equally well convert both to ints and then add.
For the operations handled here, such truncation distribution
is always safe.
It is desirable in these cases:
1) when truncating down to full-word from a larger size
2) when truncating takes no work.
3) when at least one operand of the arithmetic has been extended
(as by C's default conversions). In this case we need two conversions
if we do the arithmetic as already requested, so we might as well
truncate both and then combine. Perhaps that way we need only one.
Note that in general we cannot do the arithmetic in a type
shorter than the desired result of conversion, even if the operands
are both extended from a shorter type, because they might overflow
if combined in that type. The exceptions to this--the times when
two narrow values can be combined in their narrow type even to
make a wider result--are handled by "shorten" in build_binary_op. */
