This test is unnecessarily slow due to the CSA test suite for SwissNameDictionary doing excessive runtime calls at the moment. This causes timeouts on various bot configurations.

LiftoffCompiler::ProcessParameter assumed that by processing parameters in the order of their index, register parameters get processed first, and that for processing stack parameters it can already use all registers as temp registers. This is not true with reference type parameters, because registers always first get assigned to value type parameters even when there is a reference type parameter with a lower index. Because of this incorrect assumption register parameters were overwritten by reference type parameters on the stack that got processed first. With this CL, only those registers get used as temp registers for reference type parameters that are not used for parameters.

Take into account that the implicit rethrow at the end of a try block might unpack the exception values, and reserve enough stack space for them. This is normally done for all throwing opcodes before the switch, but 'end' is not considered a throwing opcode, which is why it needs special handling. Also clean up by factorizing the rethrow logic.

Recently we changed feedback vector allocation to be based on the bytecode size of the function. The threshold at which the feedback vectors are allocated was set to 12 * bytecode size of the function. This caused a couple of regressions on IC:duration and some regressions on other benchmarks. To avoid these regressions this cl reduces the scale factor to 8 instead of 12.

Every page that can be accessed concurrently during marking needs to be synced to avoid data races with page alloation. TraceTrait for mixins uses the object start bitmap of a page and thus requires a sync.

Port bdcd7d79 Original Commit Message: If we have baseline code, deoptimize to baseline instead of the interpreter. The process is similar to deopting to the interpreter. We just use different builtins (BaselineEnterAtBytecode/BaselineEnterAtNextBytecode) instead of InterpreterEnterBytecodeDispatch/InterpreterEnterBytecodeAdvance, that patch an interpreter frame to a baseline frame and continue execution in baseline code (based on the deopt type, at the current or next bytecode).

This is a reland of https://chromium-review.googlesource.com/c/v8/v8/+/2720300. As compared to the original version, it adds --no-stress-flush-bytecode to the const-dict-tracking.js test Original description: This CL is part of a series that implements Turbofan support for property accesses satisfying the following conditions: 1. The holder is a dictionary mode object. 2. The holder is a prototype. 3. The access is a load. This feature will only be enabled if the build flag v8_dict_property_const_tracking is set. This particular CL implements support for the case that the property in question is an accesor, meaning that the given PropertyAccessInfo has kind kAccessorDictionaryProtoConstant.

The most common case is still one of the unconditionally supported (MVP) types. Hence avoid the switch and the flags / CPU features lookup in the hot function, and offload that to a rarely called function. The fast path is now just a bit check via an EnumSet.
