In the test-run-wasm and test-run-wasm-64 cctests it is not possible to call runtime functions. To test traps in these cctests we therefore replace the runtime call with a call to a c-callback, followed by a return. This CL fixes the problem that the return did not clean up stack parameters. This CL unblocks https://chromium-review.googlesource.com/c/v8/v8/+/671008. Originally I wanted to mitigate the problem in that CL by defining an additional parameter register for arm. However, adding additional parameter registers lets other tests fail.

This is a second attempt at landing CL 644866 which was reverted by CL 667019. Extends the current implementation of WASM exceptions to be able to throw exceptions with values (not just tags). A JS typed (uint_16) array is used to hold the thrown values. This allows all WASM types to be stored (i32, i64, f32, and f64) as well as be inspected in JS. The previous CL was reverted because the WASM compiler made calls to run time functions with tagged objects, which must not be done. To fix this, all run time calls use the thread-level isolate to hold the exception being processed.

Previously, we would blindly register new handler data, leading to us leaking the old handler data. This meant we could then end up with overlapping handler data where the instruction offset and landing pads didn't line up right.

When inlining based on SharedFunctionInfo rather than based on concrete JSFunction, we weren't able to properly optimize array, object and regexp literals inside the inlinee, because we didn't know the concrete FeedbackVector for the inlinee inside JSCreateLowering. This was because JSCreateLowering wasn't properly updated after the literals moved to the FeedbackVector. Now with this CL we also have the VectorSlotPair on the literal creation operators, just like we do for property accesses and calls, and are thus able to always access the appropriate FeedbackVector and optimize the literal creation. The impact is illustrated by the micro-benchmark on the tracking bug, which goes from createEmptyArrayLiteral: 1846 ms. createShallowArrayLiteral: 1868 ms. createShallowObjectLiteral: 2246 ms. to createEmptyArrayLiteral: 1175 ms. createShallowArrayLiteral: 1187 ms. createShallowObjectLiteral: 1195 ms. with this CL, so up to 2x faster now. Drive-by-fix: Also remove the unused CreateEmptyObjectLiteral builtin and cleanup the names of the other builtins to be consistent with the names of the TurboFan operators and Ignition bytecodes.

Track whether the async arrow func parameter list was simple or not; the information is already there, we just didn't pipe it through correctly. It's needed by PreParser so that it can create the correct Scope structure. Implementation notes: - I could've used async_classifier for transmitting the "is_simple" bit, but I made it explicit (it would be unnecessary to use ExpressionClassifier for this, as we're not classifying any expressions) instead. - I'm also moving work (setting parameter_list.is_simple) from Parser to ParserBase, and adding a DCHECK in Parser to assert that the work was indeed already done.

We can constant-fold JSLoadProperty(o, i) when o is a known object (i.e. TurboFan's context specialization provides a known non-null/-undefined constant value for it), i is a known array index and o["i"] is an element on the receiver, that is non-configurable and non-writable (i.e. o was frozen using Object.freeze earlier, or o is a String object). This significantly reduces execution time of the tagged templates micro-benchmarks (ES6 and Babel transpiled), when combined with the CL https://chromium-review.googlesource.com/c/v8/v8/+/677462, it goes from templateStringTagES5: 4552 ms. templateStringTagES6: 14185 ms. templateStringTagBabel: 7626 ms. to templateStringTagES5: 4550 ms. templateStringTagES6: 616 ms. templateStringTagBabel: 589 ms. so overall a solid 23x improvement on the ES6 benchmark.

Tagged templates were previously desugared during parsing using some combination of runtime support written in JavaScript and C++, which prevented some optimizations from happening, namely the constant folding of the template object in TurboFan optimized code. This CL adds a new bytecode GetTemplateObject (with a corresponding GetTemplateObject AST node), which represents the abstract operation in the ES6 specification and allows TurboFan to simply constant-fold template objects at compile time (which is explicitly supported by the specification). This also pays down some technical debt by removing the template.js runtime support and therefore should reduce the size of the native context (snapshot) a bit. With this change in-place the ES6 version microbenchmark in the referenced tracking bug is now faster than the transpiled Babel code, it goes from templateStringTagES5: 4552 ms. templateStringTagES6: 14185 ms. templateStringTagBabel: 7626 ms. to templateStringTagES5: 4515 ms. templateStringTagES6: 7491 ms. templateStringTagBabel: 7639 ms. which corresponds to a solid 45% reduction in execution time. With some further optimizations the ES6 version should be able to outperform the ES5 version. This micro-benchmark should be fairly representative of the six-speed-templatestringtag-es6 benchmark, and as such that benchmark should also improve by around 50%.

Add padding for the interpreter registers when needed, to make the interpreter frame a multiple of 16 bytes. The padding needs to be added in the InterpreterEntryTrampoline and when generating an interpreter frame in the deoptimizer. It also needs to be considered when calculating the size of the interpreter frame during OSR and stack unwinding.
