      [inspector] Introduce debug::WasmScript · 12cdb31b
      clemensh authored 
      *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).

      [wasm] Implement official wasm text format · 172f5012
      clemensh authored 
      When disassembling functions for the inspector, we used an internal
text representation before. This CL implements the official text
format like it is understood by the spec interpreter.

Example output:
func $main (param i32) (result i32)
block i32
  get_local 0
  i32.const 2
  i32.lt_u
  if
    i32.const -2
    return
  end
  get_local 0
  call_indirect 0
end

      [inspector] Introduce translation of wasm frames · d4a42a5f
      clemensh authored 
      This allows to show wasm source (disassembled wasm code) in DevTools.
See design doc for details.

More tests for the disassembly will have to follow. Also, the text
format (generated by V8) will be changed.

      [wasm] Allocate a single script per wasm module · 32077e01
      clemensh authored 
      Before, we allocated one script per function per instance, and each
script referenced the wasm instance and the function index. Now we only
allocate one script per compiled wasm module, so the script also only
references this WasmCompiledModule, which causes changes to many interfaces.

Instead of fixing the disassemble API only used via debug.js, I decided
to drop it for now. Some later CL will reintroduce it via
DebugInterface.
