I do think it might fix a bunch of modules issues

Rereducing via PR 100129 so I don't hit the hash-table-verification issue
(which is not modules related) but rather try to find the GC issue.

However adding parameter:
--param=hash-table-verification-limit=1000
turns this error to PR99861 ICE in hashtab_chk_error

in gcc version 20210323:
All three sequences now produce "Segmentation fault" instead of "corrupted
double-linked list".
However the error "corrupted double-linked list" is still reproducible:
