Sigmund Cherem 475f55d46b Add dart2js modular test suite under a unit test. 
At this time this only compiles to .dill and then compiles from multiple modular
dill files.

Next steps: add the global split and add the modular data bits

danrubel c33f1a079e revise scanner api so that error tokens are always prepended 
This CL revises the scanner API so that tokens are always prepended
to the beginning of the token stream. This allows the parser handling
of error tokens to be simplified. Any clients using the scanner directly
rather than through the scanner API should call scannerRecovery
if the scanner has detected errors in the content.

Aart Bik 57c970d87a [dart/vm] Fix inconsistencies in intermediate representation 
Rationale:
Stricter graph checking found some dangling pointers
and missing updates. This CL fixes the omissions
and removes some bail-outs in the graph checker itself,
making the checker stricter and more consistent. Also
adds flag to control verification (avoid excessive runtimes
for large programs in general, but allows testing even
these through command line option).

an assert statement, but I was able to change that to
Nullabilitygraph.getUnconditionalUpstreamNodes).

Paul Berry 354bfb5bab Remove a few more usages of NullabilityNode._nullable. 
This will allow us to switch to the new nullability migration algorithm.

Paul Berry 933ad32baa Add logic to assertNonNullIntent to check the nullability graph. 
This will be necessary to avoid losing test coverage when we remove
the old constraint-variable based migration algorithm.

Paul Berry b05190499d Add new nullability propagation logic based on the NullabilityGraph. 
For now, we verify that the new logic produces the same results as the
old logic.  In follow-up CLs, the old nullability propagation logic
will be removed.
