Comment (by Patrick Palka <patrick@…>):

 Move the allocation of CAF blackholes into 'newCAF' (#8590)

 We now do the allocation of the blackhole indirection closure inside the
 RTS procedure 'newCAF' instead of generating the allocation code inline
 in the closure body of each CAF.  This slightly decreases code size in
 modules with a lot of CAFs.

 As a result of this change, for example, the size of DynFlags.o drops by
 ~60KB and HsExpr.o by ~100KB.
