Description of changes:
The hashing of annotations was inconsistent with equals. When the
_annotationsarray wasnullor an empty array, thenhashTypeAnnotationswould return the original hash of the value. If_annotationswas a non-empty array, but all of it's elements were null (i.e. no annotations),hashTypeAnnotations()would returnvalueHashSalt * original.This change moves the "return if no annotations" check until after we've counted the annotations in the array to make sure that a null or 0-size array is hashed equivalently to a null-element array.
