Report error if fun interface method has JVM name getFunctionDelegate

This is needed so that it wouldn't clash with the corresponding member
from the kotlin/jvm/internal/FunctionAdapter interface, which all fun
interface wrappers will implement to get proper equals/hashCode. The
workaround is to rename the fun interface method.
