With more of scalar lowering implemented, this test can now run with lowering. The only other tests that skip lowering are prototype instructions. Bug: v8:10507 Change-Id: Ia149956d2d406b6f76eb9155765474c23b89b894 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2507317Reviewed-by:

S128Select and S128AndNot relies on the inputs being lowered to I32x4, since they use Word32Xor, but it wasn't correctly specified. This means that by default, their lowered type was set to be the output's lowered type. If the result of these operations were used by F32x4ExtractLane, then their lowered type will be set to Float32x4, so the inputs will be lowered to Float32x4, and we get incorrect type of registers allocated.

Just as OS::Abort, OS::ExitProcess never returns. This is a minor cleanup which is not expected to reduce binary size considerably, since we do not call this function often. It is just nice to annotate it correctly. On windows, the {TerminateProcess} call is known to not return if called on the current process. Add an {UNREACHABLE} to enforce this.

As Wasm code increasingly needs to deal with various HeapObject subtypes, the WasmGraphAssembler is a good place to consolidate common helper methods like LoadMap or LoadFixedArrayElement. This is clearly inspired by the CodeStubAssembler, and there is clearly room for much more refactoring in this direction. This CL does not intend to change any functionality.

Main changes: - Remove the kUninitialized and kInvalidated cell type aliases. They were confusing because their meaning depended on the current value in the cell. I think kUninitialized was obsolete anyways. - Remove a DCHECK from the compiler. The property that was asserted, while true, is irrelevant. - Remove the obsolete function GetConstantType. The only left use was in the object printer, but it's pointless there because we already print the value anyways.

Add a requirement to String::GetChars that we either have a string access lock, or a string access lock is not needed. This prevents us from reading strings during internalization that may be in the middle of being made external. To avoid taking the lock too often when known to be unnecessary (e.g. for strings that were only just created), there's now a static SharedStringAccessGuardIfNeeded::NotNeeded(). This is hopefully ugly enough that it's used sparingly. One fix required for this is to enter the Isolate when tearing down IsolateData in inspector tests -- this is so that the V8Inspector instance being torn down will see the current Isolate and be able to verify its thread id against the current thread.

Instead of caching only the default formatter, cache the last used formatter if possible. This is better because it's a common use case to create a formatter in a different language and reuse it a lot, rather than create several formatters in various languages. Running the following benchmark: ``` let i = 0; function toLocaleString() { i++; return i.toLocaleString(); } i = 0; function toLocaleStringWithLocale() { i++; return i.toLocaleString('en-US'); } const functions = [toLocaleString, toLocaleStringWithLocale]; for (const f of functions) { let start = performance.now(); for (let i = 0; i < 10e5; i++) { f(); } let end = performance.now(); print(`${f.name}: ${end - start}`); } ``` sees the following improvements: With this patch: toLocaleString: 384.292 toLocaleStringWithLocale: 450.48900000000003 Without this patch: toLocaleString: 341.952 toLocaleStringWithLocale: 23439.694 This a little over 50x improvement.

The new platform can be used in combination with --single-threaded. It disables background threads and thus avoids waiting on mutexes and condition variables completely, which is useful for V8 embedders that fork the V8 process after initialization. As a bonus the new platform allows use to test --single-threaded and has already uncovered an existing bug in parallel pointer updating code.
