Proposed patch for review (JCTree.Tag)

[Kumar Srinivasan]

Nice work

2 cents,  but is it worthwhile to add a hasNotTag(ASSIGN) or 
noTag(ASSIGN) convenience method ?
this will eliminate a few negative checks, ex:

Annotate.java.
-if (args.length() == 1 && !args.head.hasTag(ASSIGN)) {
+if (args.length() == 1 && args.head.hasNotTag(ASSIGN)) {
