The guard changed from `getCurLambda() && isa<ParenExpr>(IDExpr)` to just
`isa<ParenExpr>(IDExpr)`, not to something block specific. That means any
capturing contexts, including OpenMP captured regions, etc., go through this
code now too.
Should we update the description to say the fix generalizes the rule to
capturing contexts broadly, not just blocks specifically? It looks like block
is the only context where this actually changes behavior, but please verify
that yourself.
