Ok, shared changes all look good to me so .. Reviewed: tick!

The only thing I found was a trivial issue in opto/compile.cpp which can
be ignored for now (and possibly forever):

  opto/compile.cpp

  Adding an outer if test to check UseShenandoahGC means that the inner
test of the same flag between the #ifdef ASSERT/#endif pair is now
redundant.

n.b. The Shenandoah changes look well worth having, especially the
policy choices and the ability for Shenandoah to uncommit excess heap
pages [another march stolen on G1 :-]
