SD-128 fix override checks for default methods
The check for inheriting two conflicting members was wrong for default
methods, leading to a missing error message.
We were also not issuing "needs `override' modifier" when overriding a
default method.
Removes two methods:
- `isDeferredOrJavaDefault` had a single use that is removed in this commit.
- `isDeferredNotJavaDefault` is redundant with `isDeferred`, because
no default method has the `DEFERRED` flag:
- For symbols originating in the classfile parser this was the case
from day one: default methods don't receive the `DEFERRED` flag.
Only abstract interface methods do, as they have the `JAVA_ACC_ABSTRACT`
flag in bytecode, which the classfile parser translates to `DEFERRED`.
- For symbols created by the Java source parser, we don't add the
`DEFERRED` to default methods anymore since 373db1e.
Fixes scala/scala-dev#128
