This helps triage/resolve various issues in testRuntimeErrors:
* for_non_bool_condition_test isolates the code causing a crash on the
dart2js-production-linux-d8 configuration. (See
https://github.com/dart-lang/sdk/issues/36442 and the status file.)
* for_null_condition_test will be an approved failure for all dart2js
configurations due to https://github.com/dart-lang/sdk/issues/36446.
* for_runtime_error_test contains all the remaining expected type
errors. On the dart2js-production-linux-d8 configuration (which runs
with -O3), we assume no type errors exist - even ones guarded by
Expect.throwsTypeError - so the optimized code produces runtime errors
instead. See https://dart-review.googlesource.com/c/sdk/+/97820 for a
similar discussion.
* for_test contains the remaining tests, which are valid on all dart2js
configurations.

This is a reland of 49c94d3600
It appears that the major regressions were introduced not by the typed data unification
changes but rather by 3fd124db1f "[vm] Repair the resolver abstraction." which got
reverted in e979895efb "Revert "[vm] Repair the resolver abstraction."

When disambiguating between maps and sets, ensure that `await for`
loops are marked as asynchronous. Otherwise, there will be a spurious
type error because we have a Stream and would expect an Iterable.

Invocation of == and != is only constant on receivers of types bool, int, double, and String or null operands. This is now handled correctly in constant evaluation. The case for method invocation of `a != b` is removed since it is parsed as `!(a == b)`.

The constant evaluator assumed that any ConstantExpression met during evaluation of a sub expression was not an unevaluated constant. This do occur, for instance when a field is initialized to an unevaluated constant. With the change, unevaluated constants met during evaluation are themselves evaluated.
This change also fixed handling of assert initializers in unevaluated constants.

Tests that dart2js can handle evaluation of unevaluated constants from CFE, including handling of potential compile-time errors found during evaluation.
The CL fixes a bug in the constant evaluator where it created map literals that were not marked as constant as needed.

This moves the length field as well as an inner pointer to the start of
the data into the RawTypedDataBase class. The inner pointer is updated
on allocation, scavenges and old space compactions.
To avoid writing more assembly the typed data view factory constructors
will be generated using IL, which will update the inner pointer. This
required adding new IR instructions and changing the existing
UnboxedIntConverter instruction.
This is the foundation work to de-virtualize calls on the public typed
data types, e.g. Uint8List.
