More fixes for #5654
* In stg_ap_0_fast, if we're evaluating a thunk, the thunk might
evaluate to a function in which case we may have to adjust its CCS.
* The interpreter has its own implementation of stg_ap_0_fast, so we
have to do the same shenanigans with creating empty PAPs and copying
PAPs there.
* GHCi creates Cost Centres as children of CCS_MAIN, which enterFunCCS()
wrongly assumed to imply that they were CAFs. Now we use the is_caf
flag for this, which we have to correctly initialise when we create a
Cost Centre in GHCi.
