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.

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.

Original change is in Patchset 1. I erroneously assumed DART_PRECOMPILER
was only used AOT compilation (it is also used for JIT snapshots).

We have seen scaling issues when processing many pub/sub messages
in cloud functions simultaneously, so we will limit the results messages
from a builder to 1 every 2 seconds.

This temporarily:
* sets back to opt-out all libraries in the sdk_nnbd folder until
the migration is further along
* changes the bot to use the check_nnbd_sdk script with a different libraries
file that tracks the migration progress.

99th percentile execution time is at 20s, so with twice as many results
we should still be well below the 60s timeout.
This should reduce the likelihood of lock contention on updating the
chunk count resulting in fewer builds failing to get test results.

Closes: https://github.com/dart-lang/sdk/issues/40233
This CL creates nnbd versions of the tests and runs them on the nnbd sdk.
This CL does not (1) migrate sdk_nnbd/lib/ffi fully yet, and does not (2) fix all the tests/ffi (which is NNBD tests) yet.
Uncovered new issues:
Issue: https://github.com/dart-lang/sdk/issues/40234 nullptr should have type Pointer<Never>.
Issue: https://github.com/dart-lang/sdk/issues/40247 Structs need external fields.
