Use branch instead of tailcall for recursive calls (#2282)
* Use branch instead of tailcall for recursive calls
Use a branch instead of doing a tailcall for recursive calls. This
avoids having to store the dispatch address, setting up the epilogue and
keeps guest registers in host registers for longer.
The rejit check is moved down into the entry block so that the rejit
behaviour remains the same as before.
* Set PTC version
