This change implements the MethodHandleInfo API for cracking a direct method handle back into its symbolic reference components. A DMH is any CONSTANT_MethodHandle or any result of a Lookup.find* or Lookup.unreflect* API call.
http://cr.openjdk.java.net/~jrose/8008688/webrev.04 Problem: JDK 8 (esp. Project Lambda) needs a stable API for "cracking" CONSTANT_MethodHandle constants that are involved with lambda capture sites (which are implemented with invokedynamic). Solution: Create, specify, implement, and test such an API. Run the API design past the 292 EG, the Project Lambda folks, and the Oracle internal review council (CCC). Testing: Regular JSR 292 regression tests, plus a new jtreg test with positive and 3 kinds of negative tests, in hundreds of combinations. (See below.) — John P.S. Output from RevealDirectTest.java.
