merge revision(s) 1b89b99941548fdb65305dd9a412082e7fdba45a: [Backport #17534]
Mark pattern labels as unremoveable
Peephole optimization doesn't play well with find pattern at
least. The only case when a pattern matching could have
unreachable patterns is when we have lasgn/dasgn node, which
shouldn't happen in real-life.
Fixes https://bugs.ruby-lang.org/issues/17534
