Can't profile when the heap maximum is hit

[adekoba]

$ echo "main = print $ product [1..]" > temp.hs
$ ghc -prof -auto-all temp.hs --make
$ ./temp +RTS -M100k -p -RTS
$ cat temp.prof

and the contents of temp.prof will be empty.

  * Fix #2592: do an orderly shutdown when the heap is exhausted
  Really we should be raising an exception in this case, but that's
  tricky (see comments).  At least now we shut down the runtime
  correctly rather than just exiting.
