Request for reviews (L): 6939203: JSR 292 needs method handle constants

Just -Xcomp on C1 shows up the error.  That would have been another problem in the nightlies.

With an assignment to 'k' my 292 unit tests passe with Xcomp and PatchALot, except for ldc of MH.

The -Xcomp test on both C1 and C2 gets a failure on a path through ciEnv::get_constant_by_index_impl, which I haven't written yet.  I think I'll make a separate bug for that, so as to get the ldc stuff in circulation sooner.
