* Re-arrange qv4identifier{_p.h|.cpp}Ulf Hermann2020-04-151-1/+1
| | | | | | | | | | | | QV4::IdentifierHashData doesn't need to be visible to all the clients. Furthermore, it can be completely inline. The public functions of QV4::IdentifierHash need to be out of line, but the private ones can be all inline. This shouldn't make much of a difference as most of the public functions call at least one private function. Finally, the files should be named by the class names.

| | | | | | | | | | | | | | | | | | | | | | Technically UINT_MAX is actually a valid array index, although that is an academic problem right now.
