Nicholas Nethercote c9ae38c71e Avoid unnecessary MetaItem/Attribute conversions. ... `check_builtin_attribute` calls `parse_meta` to convert an `Attribute` to a `MetaItem`, which it then checks. However, many callers of `check_builtin_attribute` start with a `MetaItem`, and then convert it to an `Attribute` by calling `cx.attribute(meta_item)`. This `MetaItem` to `Attribute` to `MetaItem` conversion is silly. This commit adds a new function `check_builtin_meta_item`, which can be called instead from these call sites. `check_builtin_attribute` also now calls it. The commit also renames `check_meta` as `check_attr` to better match its arguments.		2022-11-29 12:08:57 +11:00
