c++: redundant hashing in register_specialization
After r15-4050-g5dad738c1dd164 register_specialization needs to set
elt.hash to the (maybe) precomputed hash so that the lookup uses it
rather than redundantly computing it from scratch.
gcc/cp/ChangeLog:
* pt.cc (register_specialization): Set elt.hash.
