This adds 5% testing of 'ignition' vs 'liftoff', which tests Turbofan vs Liftoff for wasm code, and tests Ignition vs Turbofan for javascript code. It also adds 3% testing of 'liftoff' (x64) vs 'liftoff' (ia32), which does standard x64 vs ia32 testing for javascript code.

This CL renames InterpreterPushArgsMode::kJSFunction to kArrayFunction because we only ever use it for the array function. We never use PushArgsThenCall with kArrayFunction mode, so remove the unused helpers that provide the plumbing there. This is in preparation for changes to PushArgsThenConstruct, where we will no longer pass the allocation site as undefined for modes other than kArrayFunction.

Code is often being patched after creating, thus we don't need to flush the icache right away. This CL introduces a new enum to specify whether the icache should be flushed or not, and uses this in all methods which don't always need to flush. Drive-by: Fix a but where SKIP_ICACHE_FLUSH was interpreted as boolean value.

Andreas Haas authored
The multi-return tests and fuzzer used a custom call descriptor which was based on the default RegisterConfiguration. This meant that for the tests, all available registers could be used to pass parameters and to return values. This caused a problem, because in some cases we need a scratch register in the frame deconstruction. With this CL I change both the tests and the fuzzer to use the WebAssembly call descriptor. Thereby we only use 2 registers for returns, and one of the other registers can be used as scratch register. WebAssembly is the only use case at the moment which wants to return values not only through registers but also over the stack. Therefore I think it's acceptable to only test the WebAssembly usecase.

If FLAG_enable_embedded_constant_pool is false, the field for the builtin index would alias the field for the constant pool offset in the code object. This makes constant_pool() return the builtin index, but it also makes set_constant_pool() override the builtin index (and vice versa). This CL fixes this by making all constant_pool accessors honor that flag.
