RFR: 8004699 : Add type annotation storage to Constructor, Field and Method

[Joel Borggrén-Franck]

Here is the first in a series of changes to add type annotation support to reflection.

http://cr.openjdk.java.net/~jfranck/8004699/webrev.00/

While this adds overhead all instances of Field, Constructor, and Method we need this change in order to coordinate with the changes going in to HotSpot There is a plan to remove the additional overhead by consolidating all annotation fields, though this will have to wait a bit.
