The patch fixes lost IC dependencies for inherited class or interface methods.
Especially between a fake override function and its implementation.
Since IrSymbolDeserializer doesn't provide all class methods,
they are collected from the class definitions.

The patch enables the direct dependency between
fake override inline function and its implementation from the base class.
Because klibs do not keep a signature of fake override implementation,
incremental cache can not use the signature index,
therefore the signature is serialized to a cache file as is.
