Marcelina Kościelnicka	7670a89e1f	opt_clean: Better memory handling. Previously, `$memwr` and `$meminit` cells were always preserved (along with the memory itself). With this change, they are instead part of the main cell mark-and-sweep pass: a memory (and its `$meminit` and `$memwr` cells) is only preserved iff any associated `$memrd` cell needs to be preserved.	2020-10-08 18:05:51 +02:00

Previously, `$memwr` and `$meminit` cells were always preserved (along
with the memory itself).  With this change, they are instead part of the
main cell mark-and-sweep pass: a memory (and its `$meminit` and `$memwr`
cells) is only preserved iff any associated `$memrd` cell needs to be
preserved.
