Fix debugging of async code
...
Make sure the debugger finds the closure function containing the body
of async functions, but not the synthetic function that generates the
future.
Change the way the debugger sets one-time breakpoints. Instead of
compiling the function and instrumenting all safe-points, set a
breakpoint marked as “one-shot” at the beginning of the function
and wait until the function is compiled. Then, once it fires, it
gets automatically deleted.
Finally, be smarter how we resolve breakpoints in compiled code.
The compiler rearranges code in await expressions, which tripped
up the debugger. This change makes sure we select the lowest compiled
code address only within the line containing the requested breakpoint
position.

Add pause/resume for isolates in vmservice/observatory.
...
Improve the isolate view and isolate summary.
Details:
- Rig DbgMsgQueueList so it can run even when the debugger hasn't started.
- Add <action-link> element for pause/resume actions.
- Introduce new flex-percentile css classes.
- Add <isolate-run-state>, <isolate-location>, <isolate-shared-summary>, and <isolate-counter-chart> elements. Counters are now displayed as a pie chart instead of as text.
- Reorg <isolate-view> and <isolate-summary> substantially.
- Add shared style sheet to <script-view>.
- Combine pause-on-start/pause-on-exit with other debugger pause events and present a consistent representation for these in the vm service. Reorg how pause events are shown in <isolate-run-state>.
- Give the user a nicer message when an isolate is still loading.
- Move the /resume command to /debug/resume. Implement this with a bool in the Isolate class which is used to smuggle resume requests from the vm service to the dart embedding api.
- Add the /debug/pause command to the vm service
- Break the DebuggerEvent struct out into its own top-level class. Add JSON printing.
etc.

Fiddle with breakpoint resolution
...
CL https://codereview.chromium.org/233973003 fixed resolving breakpoints in code that was out of order from a compiled code address perspective, but it introduced a regression. It was no longer possible to set a breakpoint on a line that has no executable code, for example the function header. This change fixes that, and hopefully doesn’t cause any other undesirable surprises in breakpoint setting.

Don’t set more than one code breakpoint per token position
...
Some time ago when operator== calls had inlined null checks at
the call site, the debugger had to instrument multiple code breakpoints
that were all mapping to the same source position. This is no longer
necessary. This change makes sure we set a code breakpoint only at
the lowest compiled code address, so that expressions like i++ no longer
result in 2 or 3 breakpoints (one each for load filed, add, store field).
Fixes 18397.
