 Description taken from the diff:

 {{{
 SMALL_MUT_ARR_PTRS_FROZEN0 -> SMALL_MUT_ARR_PTRS_FROZEN_DIRTY
 SMALL_MUT_ARR_PTRS_FROZEN -> SMALL_MUT_ARR_PTRS_FROZEN_CLEAN
 MUT_ARR_PTRS_FROZEN0 -> MUT_ARR_PTRS_FROZEN_DIRTY
 MUT_ARR_PTRS_FROZEN -> MUT_ARR_PTRS_FROZEN_CLEAN
 }}}

 Naming is now consistent with other CLEAR/DIRTY objects (MVAR, MUT_VAR,
 MUT_ARR_PTRS).

 (alternatively we could rename MVAR_DIRTY/MVAR_CLEAN etc. to MVAR0/MVAR)

 Removed a few comments in Scav.c about FROZEN0 being on the mut_list
 because it's now clear from the closure type.
