A boolean indicating whether all known function name inferences are supported.
An integer that stores a serialization of the support object. Useful when
storing a function name (or lack thereof) for later comparisons along with
details on whether the function name was inferable at all.
Helper method for comparing bitFlags. Returns true if it is a subset of
otherFlags.
Helper method for comparing bitFlags. Returns true if it is a superset of
otherFlags.
