Clemens Backes authored
If multiple isolates were involved, we did not always hit the breakpoint reliably in all isolates. This CL fixes this flake this via two changes: 1. Remove breakpoint info when tiering up. If we keep the breakpoint information, a second isolate that later sets the same breakpoint will see that the breakpoint already exists, and will not set it again, even though the code containing the breakpoint has been replaced at that point. This fixes a flake in the debug/wasm/breakpoints test. 2. Don't overwrite code with breakpoints by default "tiered down" code. This is achieved by introducing another state in the {ForDebugging} enum which marks that code contains breakpoints. Otherwise it could happen that two isolates start tiering down (both recompiling missing functions in Liftoff), one isolate finishes and immediately sets a breakpoint, then the other isolates finishes and overwrites the code with breakpoints by the usual {kForDebugging} code. Setting breakpoints is synchronized already, so overwriting breakpoint code with other breakpoint code is always safe.

Currently, when running with --trace-turbo, V8 generates a different .json file for each wasm-to-js thunk that it compiles, but these files all have the same name "turbo-wasm-to-js-0.json", and only one file is generated. This makes it difficult to actually examine the difference in the IR for this call wrappers produced for different signatures. This patch fixes this by naming each trace file as: "wasm-to-js-<kind>-<signature>-0.json", like for example "turbo-wasm-to-js-5-ii-i-0.json".

Currently, only a scriptURL is reported, which can be over-written by sourceURL comments of the script. This means a script can basically claim to come from anywhere. This means that DevTools doesn't know the resource name the embedder provided if there is a sourceURL comment. This CL adds a `embedderName` field to the scriptParsed and scriptFailedToParse events that reports the name the embedder associated with the script.

When we add safepointing, the source position address might change. Then, we need to use the handlified version for both concurrent-inlining and not. The logic for retrieving the Handle can be encapsulated in the BytecodeArrayRef, which can be reused in the other source_position_* methods.

Using uint8_t[] causes decay to pointer issue, which manifests in copying garbage values in the call to WriteLittleEndianValue. Change it to use a std::array, which doesn't have the decaying behavior. Also add a regression test from comment#6 of the linked bug.

These functions match on specific patterns of shuffle that have more optimized implementations. Moving them out of instruction-selector allows us to reuse them in Liftoff. Most of these pattern matching functions do not depend on InstructionSelector, since they work on byte arrays. (The only one is CanonicalizeShuffle, which swaps node inputs.) This is only the first pass of moving those functions out. In particular we can clean things up more by moving the tests out of instruction-selector as well. Those will come in follow-up changes.

csuite.py compare command currently throws exception "_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)" This should fix it.
