AnnotationBeanNameGenerator was written before the introduction of the
MergedAnnotations API and therefore heavily relies on the
AnnotationMetadata abstraction and various helper methods for ASM
compatibility.
However, recent work on determineBeanNameFromAnnotation() has made it
apparent that we should use the MergedAnnotations API directly in
AnnotationBeanNameGenerator where feasible in order to avoid
unnecessary, repeated iterations/streams over the same annotation
metadata.
