all_true, any_true, bitmask, and extract_lane all replace a simd type with single scalar, so we don't need to set nullptr for the extraneous lane, and can set num_lanes to 1. So for a call node with any of the above nodes as one of its value, we were incorrectly replacing the extract lane node with 4 nodes - it should only be 1 scalar node. Drive by fix for LowerShift, it needs to check if the shift value node has replacement (e.g. if it is an extract lane node). Also we weren't setting the lowered type of a kPhi node. This can be a problem if the output of a Phi node is used by a F32x4ExtractLane and I32x4ExtractLane, which is possible (and type correct since both take v128). This will require that the output be both a float and a int, which is impossible. So fix it to Int32x4, and the uses of the phi nodes will convert appropriately. Added a test for the call node. Also tested this code by running one of our benchmarks, which exercises the Phi logic.

Add the shape (I32x4) and sign (for I8x16 and I16x8, s or u) to the name so that it is clearer what operation it is.

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.

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.
