Couple of optimizations for v128.bitselect on both ia32 and x64. 1. Remove an extra movaps when AVX is supported, since we have 3-operand instructions 2. Tweak the algorithm from: xor(and(xor(src1, src2), mask) src2) To: or(and(src1, mask), andnot(src2, mask)) It is easier to read and understand, and also eliminate a dependency chain (on kScratchDoubleReg) in the older algorithm. 3. Use integer forms of the logical ops. Older processors have higher throughput on these, compared to the floating point ops. However, the integer forms are 1 byte longer, so on SSE, we stick to the floating point ops. For AVX, this reduces instruction count from 9948 to 9868.

This replaces https://chromium-review.googlesource.com/c/v8/v8/+/2376165/. Currently JS-to-Wasm calls go through a wrapper/trampoline, built on the basis of the signature of a Wasm function to call, and whose task is to: - set "thread_in_wasm_flag" to true - convert the arguments from tagged types into Wasm native types - calculate the address of the Wasm function to call and call it - convert back the result from Wasm native types into tagged types - reset "thread_in_wasm_flag" to false. This CL tries to improve the performance of JS-to-Wasm calls by inlining the code of the JS-to-Wasm wrappers in the call site. It introduces a new IR operand, JSWasmCall, which replaces JSCall for this kind of calls. A 'JSWasmCall' node is associated to WasmCallParameters, which contain information about the signature of the Wasm function to call. WasmWrapperGraphBuilder::BuildJSToWasmWrapper is modified to avoid generating code to convert the types for the arguments of the Wasm function, when the conversion is not necessary. The actual inlining of the graph generated for this wrapper happens in the simplified-lowering phase. A new builtin, JSToWasmLazyDeoptContinuation, is introduced to manage lazy deoptimizations that can happen if the Wasm function callee calls back some JS code that invalidates the compiled JS caller function.

AVX has 3-operands shuffle/unpack operations. We currently always require that dst == src0 in all cases, which is not required if we have AVX. For the arch shuffles that map to a single native instruction, add support to check for AVX in the instruction-selector, to not require same as first, and in the code-gen to support generating AVX. The other arch shuffles are slightly more complicated, and can be optimized in a future change.

An improvement to generic shuffle improvement (https://crrev.com/c/2152853) required a temporary SIMD register to hold the mask, rather than pushing it onto a stack. The temporary register requires that we UseUniqueRegister on the inputs, to prevent aliasing, as we will write to the temp. However, we only need this for the generic shuffle. We accidentally over-constraint all other pattern matched shuffles, since they don't use any temps. On a ~2000 line function containing ~150 shuffles (not all of which are generic shuffles), we get 16 less instruction in the native code, and actually see a very small improvement in the overall benchmarks.

We can have more optimizations for this instruction, they leave some junk in the top lanes of dst, but that doesn't matter: - when lane is 1: we use movshdup, this is 4 bytes long - when lane is 2: use movhlps, this is 3 bytes long - otherwise use shufps (4 bytes) or pshufd (5 bytes) All of which are better than insertps (6 bytes).
