[dart/vm] enhanced graph checker

Rationale:
Refactored existing verify uses (with some overlap and some
additional checks) into the graph checker. Also added more
verification code and repaired some inconsistencies in IR
found by new checker. However, some checks are disabled with
a TODO, since the IR does not currently meet all the stricter
assumptions. Fixes will follow.
