On 1/27/20, the nnbd specification changed weak and strong mode instance checks
to make them behave uniformly across legacy and opted-in libraries.
Therefore, it is not necessary anymore to propagate the library mode in
generated code to the runtime.

Previously, each top level key/value pair in the file represented a
feature, so in order to make room for the new field, these were all
moved under a "features:" header.
Code generators have been updated to produce the same result as they
did before; in future CLs I'll update them to generate code based on
the new field.

Since we transitioned to natives for dart:html, manually written native
fields should be rewritten. Similarly, if there are fields in abstract
classes that represent interfaces, they should be converted. Fields in
abstract classes that are used in that class are left alone.

New analyzer errors are reported for dart:html around nullability.
Non-nullable fields are translated to native getters and setters if part
of a concrete class and normal getters and setters if abstract.

NNBD fields that were non-nullable or final were transformed to getters
so that they were compilable. They need to be transformed to natives now
for performance.

This changes how we used String.fromEnvironment to enable tracing.
With null-safety http://dartbug.com/40678 means that these constants are
never null, so we were accidentally enabling tracing by default.
I was only able to see this when running dart2js from source
(which affects the hostasserts configuration), but I wasn't seeing this
when running from snapshot. We need to investigate that separately.

Running tools/test.py locally behaves differently than on the bots
because the bots will have special environment variables set.
=> We want also local runs of tools/test.py to report ASAN errors, so
this CL moves the setting of environment variables to tools/test.py
Furthermore we enable "additional check_initialization_order=true" asan
option to detect ordering issues when initializing global state.
Make the IsolateGroup::isolate_group_random_ heap allocated on VM
startup to avoid initialization ordering issue (turns out our `Random`
can depend on embedder entropy source callback being available)
Also add locking around assigning of isolate group ids -- without it we
could have two threads racing and possibly getting the same id.

CSSStyleDeclaration.getPropertyValue returns a non-nullable string.
It will also return an empty string if the property is not found. Since
getPropertyValue returns the value of the native getPropertyValue, the
null check should be removed.

Preexisting comments on multi-line errors modify the length of the error
reported from the analyzer since it includes the comments in between. So
the error length increases every time you run this script, making the
error comments unwieldly.

In the legacy SDK these two methods in ListMixin take Object, not E.
When I migrated them to NNBD, I changed them to E to match the
declaration of the methods in List. This was an unintended breaking
change.
Fix that by changing them to "Object?", which is the NNBD equivalent of
the declarations in the legacy SDK.

Sets a threshold of five continuations determining if the old
if-else or the new igoto-based implementation will be used.
Informal benchmarking on x64 and arm_x64 point towards the overhead
of the igoto-based impl. dropping off around this point.
Benchmarks of this CL (threshold=5) show drastic improvement in
Calls.IterableManualIterablePolymorphicManyYields of about ~35-65%
across {dart,dart-aot}-{ia32,x64,armv7hf,armv8}.
Note: This is a second revision of a CL landed and reverted from:
https://dart-review.googlesource.com/c/sdk/+/133586
The fix for the previous revert was swapping the parameters to
BuildIndirectEntry(int, int) in kernel_binary_flowgraph.cc.
