[NFC][InstCombine] Fine-tune 'check for [no] signed truncation' tests
We are using i8 for these tests, and shifting by 4, which is exactly the half of i8. But as it is seen from the proofs https://rise4fun.com/Alive/mgu KeptBits = bitwidth(%x) - MaskedBits, so with using shifts by 4, we are not really testing that we actually properly handle the other cases with shifts not by half... llvm-svn: 337208
