index to fix VMs coverage issue
This CL fixes the VM not always reporting coverage for mixin usages
properly.
* When asking the VM for coverage you can do it in one of two ways
* Ask the VM for coverage for everything; or
* Ask the VM for coverage for a specific script
* Asking the VM for coverage for everything works perfectly fine.
The VM goes through everything and reports coverage correctly.
* Asking the VM for coverage for a specific script (which is, at least
now, what the flutter tools does) doesn't work in the simple mixin
case described at http://dartbug.com/39779: The VM goes through the
libraries, asking for the list of scripts they "know about",
and checks for matches against what you asked for.
In this case, when asking for 'master.dart', the library for
'lib.dart' says no when it shouldn't --- because of the way the mixin
transformation works the content is actually in lib.dart.
This CL updates the content of the field 'sourceReferences' on Library
to fix the issue.
Fixes#39779

When creating a KernelProgramInfo, we create several logical views into the kernel buffer. These are fresh ExternalTypedDatas, rather than proper TypedDataViews, so they do not automically keep the original ExternalTypedData alive. Create an explicit reference to the orginal ExternalTypedData in the KernelProgramInfo. When creating snapshots, this reference is ignored/null'd and the views are turned into copies, effectively dropping the parts of the original buffer that do not have views.
Fixes a leak with reload and a use-after-free with eval.

When CPU profiling is disabled, the getCpuSamples RPC would return with
a ServerRpcException stating that the profiler was disabled. This wasn't
being caught when the RPC was invoked, but was being caught in
`ObservatoryApplication` and swallowed. This resulted in the timeline
page being stuck at the timeline loading dialog.
Also includes fixes from "[observatory] Properly wait for Catapult's iframe to load. Give
message while fetching timeline.", commit 3b99524167, which was reverted.

Setting the `enableTimelineLogging` property of `HttpClient` to true results in
timeline events being created for HTTP connections and HTTP requests.
Timeline events contain general connection information, including:
- Request type
- Status code
- Request / response headers
- Cookies
- Non-sensitive proxy information
- Relevent error messages for failed connections

This is practically a copy of the change in
https://dart-review.googlesource.com/c/sdk/+/118040 but applied to the non-nnbd
sdk.
Even though there is no intent to run the non-nnbd sdk with the non-nullable
experiment, we need to add this annotation because of how we
intend to gradually start testing NNBD. The libraries.json under
sdk_nnbd is allowed to point to libraries under the non-nnbd sdk in order to
temporarily build without errors until all patch files are migrated and all CFE
issues are addressed.

We attempted to delete the file with service protocol information
immediately after retrieving the URI. However, the spawned process could
potentially still have that file open which will cause the deletion to
fail on Windows. Fix is to wait until the process closes before deleting
to ensure it's not holding onto the file.

Disabling the profiler will **not** release the sample buffer on Linux,
MacOS, and other platforms which utilize signals for profiling as
there's no way to ensure all signals have been receieved after the
thread interrupter has been shutdown.

Specifying a parent will result in an argument being added to 'start'
events for that TimelineTask named 'parentId', which contains the task
ID of the parent. This is to be used by DevTools to show relationships
between asynchronous tasks that are not currently supported in the trace
event format used by Catapult.

This function has been unused for a long time.
Also, computing fingerprints for bytecode function causes bytecode to be loaded, which can lead to an old enum class being initialized with enum values for the new enum class, causing a forwarding loop when migrating enum values.

This improves the time to deserialize a snapshot. It also doubles the memory needed to receive the snapshot buffer, but the memory high water mark is still computing the dominators.
