Craig Topper 34da12dd1f [DAGCombiner] Remove (sra (shl X, C), C) if X has more than C sign bits.
If sext_inreg is supported, we will turn this into sext_inreg. That
will then remove it if there are enough sign bits. But if sext_inreg
isn't supported, we can still remove the shift pair based on sign
bits.

Split from D95890.
