Combined this and the checker of
SUPERTYPE_INITIALIZED_WITHOUT_PRIMARY_CONSTRUCTOR together.
Also fixed SUPERTYPE_INITIALIZED_WITHOUT_PRIMARY_CONSTRUCTOR incorrectly
repoted as warning instead of error.
This commit introduces several different things, in particular:
- check type arguments in expressions
- new TypeArgumentList node to deal with diagnostic source
- ConeDiagnostic was moved to fir:cones
- ConeIntermediateDiagnostic to use in inference (?) without reporting
- detailed diagnostics on error type
