Fold (sext (truncate x)) more aggressively, by avoiding creation of a
sextinreg if not needed. This is useful in two cases: before legalize,
it avoids creating a sextinreg that will be trivially removed. After legalize
if the target doesn't support sextinreg, the trunc/sext would not have been
removed before.
