So, I can see the performance statistics during tests, but in the

As part of the implementation of
https://github.com/dart-lang/language/issues/731 (improved inference
for fold etc.), I expanded the front end's type inference logic so
that instead of just having a downward phase and an upward phase, it
could have 3 or more phases. The function that previously did
downward inference became repurposed to do "partial inference" (which
could either be the first, downward stage, or a later, horizontal
stage). However, I failed to generalize the logic that prevents types
assigned by one inference stage from being refined by later
stages--previously this logic was only needed for upward inference,
but now it's needed for horizontal inference stages as well. (This
logic is needed because of Dart's "runtime checked covariance"
behavior--it means that we want to stick with the type from downward
inference, even if a later horizontal inference stage is able to find
a more precise type, because that more precise type may lead to
runtime failures).
As part of this change I've re-architected the inference methods so
that they are responsible for creating and returning the list of
inferred types. This makes the inference logic more similar between
the front end and analyzer, and is easier to read IMHO. The total
number of list allocations is the same as before.

The front end desugars extension methods by inserting a synthetic
`this` argument before all other arguments. But this synthetic
argument isn't included in the `formalTypes` and `actualTypes` arrays.
So when recording a value into
`_DeferredParamInfo.evaluationOrderIndex` we may need to subtract 1 in
order to ensure that later logic will find the correct argument.
Fixes a corner case of https://github.com/dart-lang/language/issues/731.

This adds a --platform= option to dart2wasm to read the SDK libraries
from that dill file instead of compiling them from source every time.
If the option is not given, the SDK libraries are compiled, like before.
Also adds a "dart2wasm" build target, which will build the dart2wasm
platform dill and compile dart2wasm to two AOT snapshots (with and
without asserts). The dart2wasm scripts in sdk/bin are updated to run
via these snapshots and use this platform dill.
This speeds up test runs for the dart2wasm-hostasserts-linux-x64-d8
configuration by approximately 45x.
