[runtime] Optimize and unify rest parameters. Replace the somewhat awkward RestParamAccessStub, which would always call into the runtime anyway with a proper FastNewRestParameterStub, which is basically based on the code that was already there for strict arguments object materialization. But for rest parameters we could optimize even further (leading to 8-10x improvements for functions with rest parameters), by fixing the internal formal parameter count: Every SharedFunctionInfo has a formal_parameter_count field, which specifies the number of formal parameters, and is used to decide whether we need to create an arguments adaptor frame when calling a function (i.e. if there's a mismatch between the actual and expected parameters). Previously the formal_parameter_count included the rest parameter, which was sort of unfortunate, as that meant that calling a function with only the non-rest parameters still required an arguments adaptor (plus some other oddities). Now with this CL we fix, so that we do no longer include the rest parameter in that count. Thereby checking for rest parameters is very efficient, as we only need to check whether there is an arguments adaptor frame, and if not create an empty array, otherwise check whether the arguments adaptor frame has more parameters than specified by the formal_parameter_count. The FastNewRestParameterStub is written in a way that it can be directly used by Ignition as well, and with some tweaks to the TurboFan backends and the CodeStubAssembler, we should be able to rewrite it as TurboFanCodeStub in the near future. Drive-by-fix: Refactor and unify the CreateArgumentsType which was different in TurboFan and Ignition; now we have a single enum class which is used in both TurboFan and Ignition.
