Fix an inconsistent state, between the in_common attribute
and the common_block pointer.
- adding a symbol to a common block list in gfc_match_common is delayed
after the call to gfc_add_in_common.
- gfc_restore_latest_undo_checkpoint is changed to check the common_block
pointer directly instead of the in_common attribute.
- gfc_restore_old_symbol is changed to also restore
the common-related pointers. This is done using a new function created
to factor the related memory management.
- In gfc_restore_last_undo_checkpoint, when a symbol has been removed
from the common block linked list, its common_next pointer is cleared.
