[inspector] Refactor protocol-test.js This refactoring makes it easier to write advanced tests and gives full control over what's happening to the test code. It also forces description for every test. BUG=none Review-Url: https://codereview.chromium.org/2891213002 Cr-Commit-Position: refs/heads/master@{#45412}

Tests how wasm scripts are reported
Remove fake wasm scripts from V8 backend Inspector will no longer report per-function wasm scripts or provide wasm disassembly. Locations in wasm are now consistently reported through the inspector API as lineNumber=0 columnNumber=byte offset in module.

Check that each inspector gets a wasm script at module creation time.
Support .external_debug_info symbol references Wasm modules generated by emscripten today have two ways to point to debug symbol files, the source mapping url and external debug info custom sections. To support both, this CL extends CDP to appropriately report the symbol type and location.

[wasm] Pretend that DWARF section is a fake source map Unfortunately, codebase contains lots of places that use one of the two formats as an internal representation for Wasm locations: 1) {line: 0, column: byte offset within entire module} 2) {line: function index, column: byte offset within function} These places choose these formats interchangeably and convert from one to another depending on the presence of source map URL in Wasm. This is not very convenient and makes it hard to add support for DWARF which should behave just like Wasm with source maps - that is, report a raw Wasm script instead of fake scripts per each disassembled function, and use representation (1) instead of (2) internally. I tried to refactor these locations and avoid checking for source map URLs in the previous CL - https://crrev.com/c/v8/v8/+/1833688. However, it quickly got out of hand, and updating code in one place just kept revealing yet another that gets broken by the changes, so I made a decision to abandon it and leave to someone who knows the codebase better. Instead, this CL is based on https://crrev.com/c/v8/v8/+/1809375, but, rather than trying to integrate DWARF separately and only for supported agents, it pretends that encountering DWARF section is the same as encountering a `sourceMappingURL` section with fake URL "wasm://dwarf". This ensures that Wasm with DWARF behaves exactly in the same way as Wasm with source maps, just like we want, with minimal changes to the codebase. The only downside is that frontends without DWARF support won't get even a disassembled version of Wasm that contains DWARF info. This is unfortunate, but, as per previous discussions, should be fine given current state of Wasm debugging.

To support both, this CL extends CDP to appropriately report the symbol type and location.

[wasm] Prefer source map over DWARF info if present Some tools that transform Wasm today, already support encoding the transforms and correctly updating locations in source maps, but not yet in DWARF (although this is being worked on). Until they catch up, it's best to consistently prefer source maps over DWARF when both are present, and not just rely on order of sections as accidentally done in the previous CL that introduced DWARF info.

[strings] Reclaim a bit in the hash field By replacing usage of the IsNotArrayIndex bit with IsNotIntegerIndex, we get back one bit that we can use to increase the number of hash bits stored. The price is that strings that represent array/integer indices beyond the cacheable range will have to be scanned more often, but these strings should be rare, and we expect that the additional hash bit is more worthwhile to have.

Add support for reporting raw Wasm scripts This addition will allow to experiment with parsing DWARF information from WebAssembly on the frontend side for improved debugging. The frontend must explicitly opt-in to this experiment by setting `supportsWasmDwarf: true` in `Debugger.enable` params. When this option is present, and Wasm appears to contain DWARF information (heuristic: `.debug_info` custom section is present), V8 will not try to disassemble and report each WebAssembly function as a separate fake script, but instead will report Wasm module as a whole. Note that V8 already does this when Wasm is associated with a source map. Additionally, this CL adds a dedicated `Debugger.getWasmBytecode` command that accepts scriptId and returns raw wire bytes of the chosen WebAssembly module.
