cprop_hardreg: Enable propagation of the stack pointer if possible
Propagation of the stack pointer in cprop_hardreg is currenty
forbidden in all cases, due to maybe_mode_change returning NULL.
Relax this restriction and allow propagation when no mode change is
requested.
gcc/ChangeLog:
* regcprop.cc (maybe_mode_change): Enable stack pointer
propagation.
