  ParseAPI: Speed up the case where a function is called from many locations (#1190)

In some binaries a single function has many callers, so copying out the source edges for
the entry Block takes a while and causes significant contention on the Block's lock.
The case in Parser::finalize where this becomes a hotspot likely does not need to read
every edge, so this commit inlines those cases into methods on Block instead.
