[vm/compiler] Introduce graph checker

Rationale:
This is a start with a graph checker that verifies
the consistency of the flow graph after each compiler
pass with the goal of detecting errors as early as
possible. The checks add overhead, so are only run
in debug mode. The objective is that all written
and unwritten assumptions on the flow graph that
are relatively easy to check will be converted
into actual code.
