Fix two bugs in stg_ap_0_fast in profiling runtime
This includes two bug fixes in profiling version of stg_ap_0_fast:
- PAPs allocated by stg_ap_0_fast are now correctly tagged. This
invariant is checked in Sanity.c:checkPAP.
(This was originally implemented in 2693eb11f5, later reverted with
ab55b4ddb7 because it revealed the bug below, but it wasn't clear at
the time whether the bug was the one below or something in the commit)
- The local variable `untaggedfun` is now marked as a pointer so it
survives GC.
With this we finally fix all known bugs caught in #15508. `concprog001`
now works reliably with prof+threaded and prof runtimes (with and
without -debug).
