RFR(S): 8026694: New type profiling points break compilation replay

If we want to still be able to read replay files generated before this change, the assert:

src/share/vm/ci/ciReplay.cpp
1120       assert(m->_data_size + m->_extra_data_size == rec->_data_length * (int)sizeof(rec->_data[0]), "must agree”);

needs to removed or changed (extra data from the MDO is not currently dumped).
