review request (M): 7056328: JSR 292 invocation sometimes fails in adapters for types not on boot class path

[John Rose]

This is a possible fix for a JSR 292 bug in JDK 7.

http://cr.openjdk.java.net/~jrose/7056328/webrev.00/

Bytecodes produced by MethodHandleWalk will incorrectly scope names off the boot class path.  The fix is to specially process the constant pool of such bytecodes, by "pre-resolving" the affected entries.

The fix includes new stress test logic (debug build only) for running every method handle created through MHW and the JIT.

Testing so far:
 - JDK regression tests with and without the new stress modes
 - Tom's local tests (on previous version)
 - fixes customer problem (Ola Bini's NoClassDefFound error)
