Status of tests which now start failing has been updated.
Ability to run the vm tests in strong mode has also been added. The
status of tests which fail in strong mode will be updated when the vm
tests are moved under the strong mode tests on the bots.

This CL corrects handling of overflows in range analysis to
account for wrap-around (which happens with new integer semantics).
* If there is an overflow while doing computations in range
analysis, the resulting range is approximated as full int64 range.
* For symbolic range boundaries 'symbol + offset', offset is checked
to stay within [kMinInt64 - kSmiMin, kMaxInt64 - kSmiMax] in order
to guarantee that overflow doesn't occur.

The `$builder_tag == strong` annotations were added before test.py
supported `$strong`. Now that `$strong` is supported, it's better to
use it directly to avoid confusion.

This relands 75a9579ea0.
The approach works as follows:
Step 1: Kernel transform. Under the closed world assumption compute the
set of selectors dispatched dynamically, then mark all procedures that don't
match any of those selectors as 'not-dispatched-dynamically'.
Step 2: VM backend. When building IR for a function if this function was
marked as not-dispatched-dynamically then omit type checks for any parameter
that is not marked as generic-covariant-impl, as such arguments are guaranteed
to be checked on the caller side (by front-end).

* Flutter gallery Instructions size is reduced by 11% (8748720 bytes to 7846368 bytes).
Baseline is at 6196496 bytes.
Alternatively to annotating individual procedures, I considered annotating Program node
with a set of dynamically dispatched selectors. Decoding and passing this information
around proved to be quite cumbersome in the "streaming" world, so I opted for a simpler
approach where all individual procedures are annotated.

When AOT call specializer computes single target for a method
invocation it needs to ignore artificial methods like field
dispatchers and method extractors that are lazily injected
by the precompiler as compilation of the whole application
progresses.
Lazy injections means that we don't have complete knowledge
when we compile a single method.
