[PR87815]Don't generate shift sequence for load replacement in DSE when the mode size is not compile-time constant
The patch adds a check if the gap is compile-time constant.
This happens when dse decides to replace the load with previous store value.
The problem is that, shift sequence could not accept compile-time non-constant
mode operand.
