review for 7105305: assert check_method_context proper context

[Tom Rodriguez]

This may causes some other CTW issues but I will file separate bugs for those, unless they have a simple fix I can include here.

7105305: assert check_method_context proper context
Reviewed-by:

preload_and_initialize_all_classes intends to initialize all
instanceKlasses but is using the wrong check.  Fixing that exposes a
bug in the dependencies where the is_concrete_method isn't checking
for is_static.  The fix is to make it consistent with the ciMethod
variant.  Tested with full CTW.
