ticky enhancements * the new StgCmmArgRep module breaks a dependency cycle; I also untabified it, but made no real changes * updated the documentation in the wiki and change the user guide to point there * moved the allocation enters for ticky and CCS to after the heap check * I left LDV where it was, which was before the heap check at least once, since I have no idea what it is * standardized all (active?) ticky alloc totals to bytes * in order to avoid double counting StgCmmLayout.adjustHpBackwards no longer bumps ALLOC_HEAP_ctr * I resurrected the SLOW_CALL counters * the new module StgCmmArgRep breaks cyclic dependency between Layout and Ticky (which the SLOW_CALL counters cause) * renamed them SLOW_CALL_fast_<pattern> and VERY_SLOW_CALL * added ALLOC_RTS_ctr and _tot ticky counters * eg allocation by Storage.c:allocate or a BUILD_PAP in stg_ap_*_info * resurrected ticky counters for ALLOC_THK, ALLOC_PAP, and ALLOC_PRIM * added -ticky and -DTICKY_TICKY in ways.mk for debug ways * added a ticky counter for total LNE entries * new flags for ticky: -ticky-allocd -ticky-dyn-thunk -ticky-LNE * all off by default * -ticky-allocd: tracks allocation *of* closure in addition to allocation *by* that closure * -ticky-dyn-thunk tracks dynamic thunks as if they were functions * -ticky-LNE tracks LNEs as if they were functions * updated the ticky report format, including making the argument categories (more?) accurate again * the printed name for things in the report include the unique of their ticky parent as well as if they are not top-level

Fix non-termination of SpecConstr (see #5550). ForceSpecConstr will now only specialise recursive types a finite number of times. There is a new option -fspec-constr-recursive, with a default value of 3.
