gdb: maintain ptid -> thread map, optimize find_thread_ptid
When debugging a large number of threads (thousands), looking up a
thread by ptid_t using the inferior::thread_list linked list can add up.
Add inferior::thread_map, an std::unordered_map indexed by ptid_t, and
change the find_thread_ptid function to look up a thread using
std::unordered_map::find, instead of iterating on all of the
inferior's threads. This should make it faster to look up a thread
from its ptid.
