Initialize a new name cache
This is a version of newNameCache that lets you supply your own unique tag and set of known key names. This can go wrong if the tag supplied is one reserved by GHC for internal purposes. See #26055 for an example.
Use newNameCache when possible.
Deprecated. Use newNameCache or newNameCacheWith instead
This takes a tag for uniques to be generated and the list of knownKeyNames These must be initialized properly to ensure that names generated from this NameCache do not conflict with known key names.
Use newNameCache or newNameCacheWith instead
