Fixed 6896727: nsk/logging/LoggingPermission/LoggingPermission/logperm002 fails with G1, EscapeAnalisys

Problem:
EA incorrectly allows to bypass one memory store by an other
without updating its users. As result node's memory references
could missing on some paths.

Solution:
When updating input memory edge for a store move
its memory users to corresponding memory slices.
I also added several asserts to verify correctness
of memory splitting during EA.
