cprop_hardreg: Ensure replacement reg has compatible mode [PR99221]

In addition to the existing check also ask the target whether a
replacement register may be accessed in a different mode than it was set
before.

gcc/ChangeLog:

* regcprop.c (find_oldest_value_reg): Ask target whether
  different mode is fine for replacement register.
