JDK-8341779

`TypeMirror` Changed to Provide Annotations for Types Loaded from Bytecode


The implementation of TypeMirror now provides access to annotations for types loaded from bytecode. Previously type annotations were not associated with types loaded from bytecode.

Annotation processors can access type annotations for elements using AnnotationMirror#getAnnotationMirrors, and the annotations will be included in the output of AnnotationMirror#toString.

Any programs that relied on annotations being omitted for elements loaded from the classpath should be updated to handle type annotations.
