Title: Cleaned up stale tags and untagged passing ones.

Turns out there were many tags without the corresponding tests.
Also, a few tests were tagged as failing, but were actually failing.
Left out unstable ones about threads and external environment encoding.
There might be some I didn't know they're unstable/unsafe to delete, if so, please let me know.
