With creation frame we can show additional information with description of each async stack trace, which could help user to understand where promises were chained.
At least in case of Promise.resolve().then(foo1).then(foo2) we would be able to show following stack trace for break in foo2 callback:
foo2 (test.js:14:2)
-- Promise.resolve (test.js:29:14)--
-- Promise.resolve (test.js:28:14)--
promiseThen (test.js:30:2)

*and* report all "virtual" wasm scripts right when the wasm script is
registered at the inspector.
WasmScript is a subtype of Script, with the cast checking that it is
actually a wasm script.
This layout makes it quite easy to implement functionality that is only
available for wasm scripts, and allows to later directly use the
WasmCompiledModule instead of the i::Script for backing the
debug::WasmScript. We might also add virtual methods to
provide different implementations for GetSourcePosition, Source and
others.
DisassembleWasmFunction now also becomes a method of this class instead
of a static function on the DebugInterface.
The WasmTranslation now uses the new WasmScript type instead of the
Script wrapper, and also registers all virtual wasm scripts immediately
when the wasm script is made public to the inspector (when the wasm
module is created).

This method iterates through all shared function info which are related to passed script, compiles debug code for SFI in range if needed and returns possible break locations.

In the asm.js to wasm pipeline, we generate an entry function with
BUILTIN code, but still attached to a TYPE_NORMAL script.
This fix avoids trying to set a breakpoint there, resulting in a crash
on DCHECK(shared->HasDebugInfo()).
Also add two inspector tests to track regressions.

To achieve this:
- fixed crash on windows - String16::fromInteger used "%zu" which doesn't support by VS2013 compiler, wrapped with ifdef else.
- fixed asan for d8 - unique_ptr on array has single element type.
- force Debugger.disable at the end of test.
