Fixed 6953267: assert in EA code with -XX:+StressReflectiveCode

EA code does not handle code generated with StressReflectiveCode
when an array klass is used for Allocate node or instance klass
for AllocateArray node on never executed path (see method
LibraryCallKit::inline_native_clone()).

Add missing checks into EA code.
