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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34621 91177308-0d34-0410-b5e6-96231b3b80d8
