With recent CLs we always store maximum N async stack traces and when we reach limit we drop half of them.
Current promise collected event requires creating weak handle:
- it takes time,
- it consumes memory.
Since async task id distribution for promises is uniform (each new promise has last_async_task_id + 1 as an id) our hash map is good enough to handle any amount of async task ids, following time of executing 1 000 000 000 of lookups:
- for empty hash map: 1.45 seconds,
- for hash map with one entry: 14.95 seconds
- 1024 entries: 15.03 seconds
- 1024 * 1024 entries: 14.82 seconds
- 1024 * 1024 * 1024: 17.9 seconds

What will we get:
- console would be included into snapshot and allow us to reduce time that we spent in contextCreated function (~5 times faster),
- it allows us to make further small improvement of console methods, e.g. we can implement super quick return from console.assert if first argument is true,
- console calls are ~ 15% faster.

This CL implements the proposed change to show information about
WebAssembly values and call frames via the inspector interface.
Each interpreted WebAssembly frame will have two scopes: A global scope
showing information about the memory (to be extended for globals), and
a local scope showing information about parameters, local variables, and
stack values.
Names of local variables will be added later.

The format of the name section changed recently. It now contains
subsections of different type (currently for function names or local
variable names).
This CL changes our internal wasm module builders (in JS and C++) to
emit this new format, and changes the decoder to understand it.
We currently only parse the function name section, and ignore names of
local variables. I will later extend this to parse local variable names
when needed for debugging.

It allows us to implement console methods without taking in account how and where we create and store these methods:
- later we can move console object implementation to builtins..
- ..and install command line API methods smarter.

With precise binary code coverage, the reported count is either 0 or 1.
We only report 1 the first time we collect coverage data after the
function has been executed.
Since we do not care about the accurate execution count, we can optimize
the function once it has been executed once.
Also change best effort coverage to be implicitly binary.
