When AVX2 is available, we can use vbroadcastss. On AVX, use vshufps, since it is non-destructive. On SSE, shufps is 1 byte shorter. FIXED=b/175364402 Change-Id: I5bd10914579d8db012192a9c04f7b0038ec1c812 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2599849Reviewed-by:

Previously we had introduced a special `v8::internal::WasmValue` type which we used to expose Wasm values to the Scope view in Chromium DevTools. The problem however is that these values cannot be exposed to JavaScript (and in particular not to Debug Evaluate), which means that particularly for v128 and i64 we have inconsistent representations across the various parts of DevTools. This change removes the `wasm` type from the RemoteObject and all the adjacent logic, and paves the way for a uniform representation of Wasm values throughout DevTools. For i64 we will simply use BigInt consistently everywhere, and for i32, f32 and f64 we'll just use Number. For externref we will represent the values as-is directly. For v128 values we currently use a Uint8Array, but will introduce a dedicated WasmSimd128 class in a follow-up CL.

There's a bit more work to do to add support for import assertions for dynamic import(). This is the first of a series of changes to do that. This adds parser support for the form of import() that takes import assertions per https://tc39.es/proposal-import-assertions/#prod-ImportCall A future change will pass the assertions expression along to Runtime_DynamicImportCall where the assertions will be unpacked and filtered per Isolate::supported_import_assertions_.

This implements the spec change in https://github.com/tc39/ecma262/pull/2164 Making TA elements configurable has interaction with delete. While the elements are configurable, they are only "deletable" via detaching the underlying ArrayBuffer, not via `delete`. That is, `delete ta[idx]` for an in-bounds `idx` still returns false.

When bytecode gets flushed from SFI and we generate the bytecode again, we expect that the generated bytecode is exactly the same as the earlier bytecode. We reuse the same closure feedback cell array allocated earlier and hence it is required that number of closure feedback slots remain the same. This cl just adds a CHECK for that, so we fail when this is not the case.

Due to the transition to the jobs API, WebAssembly compilation was using background threads, even when --single-threaded and therefore --wasm-num-compilation-tasks=0 was used. With this CL, the compilation job is started with a maximum concurrency of 0 when --wasm-num-compilation-tasks=0. To ensure compilation progress in asynchronous compilation, the main thread waits for baseline compilation to finish right after initializing all compilation units, and thereby participates in the compilation.

Port bbb1b345 Original Commit Message: Adds support for emitting data with a reloc info to enable support for HeapObjects for immediate deopt args, required by dynamic check maps. In order to do this, a new DATA_EMBEDDED_OBJECT relocinfo type is added. This represents a raw object inserted into the instruction stream. For x64/ia32 it is treated the same as FULL_EMBEDDED_OBJECT, but on Arm/Arm64 this behaves differently since it points directly to the embedded object pointer rather than to an instruction that loads it.
