Determines whether a given calling convention is valid for the target.
A calling convention can either be accepted, produce a warning and be substituted with the default calling convention, or (someday) produce an error (such as using thiscall on a non-instance function).

The first value in the pair is the minimum offset between two objects to avoid false sharing (destructive interference).
The second value in the pair is maximum size of contiguous memory to promote true sharing (constructive interference). Neither of these values are considered part of the ABI and can be changed by targets at any time.

Determine whether the _BitInt type is supported on this target.
This limitation is put into place for ABI reasons. FIXME: _BitInt is a required type in C23, so there's not much utility in asking whether the target supported it or not; I think this should be removed once backends have been alerted to the type and have had the chance to do implementation work if needed.
