Currently, the runtime IC functions deduce the IC kind and the language mode from the feedback slot kind. To support feedback free execution (for V8 lite mode and lazy allocation of feedback vectors) we need to infer the IC kind even when feedback vectors are not present. To be able to infer the language mode without feedback vectors, this cl forces context allocation in cases where we raise the language mode in the middle of a function. The language mode is the stricter of the language mode on the SFI and the language mode of the current context. This cl updates the bytecode handlers to check for valid feedback vectors and to call into runtime if the feedback vector is not allocated. It also adds new runtime functions to be able to infer the IC kind when there is no feedback vector. Most of the builtins and handlers remain unchanged because they are only used when feedback vector is present.

Bytecode flushing can overwrite a bytecode array with an UncompiledDataWithoutPreParsedScope.

To allow any-ref parameters, we have to make sure that any-ref stack parameters get seen by the GC. This CL is a first step into that direction. The goal of this CL is to group any-ref parameters at the stack side of the parameters. This means that in the stack frame iterator we do not need information about where anyref parameters are in the stack frame. We only need information about how many anyref parameters there are at the bottom of the stack frame.

This CL merges MicrotaskContext management into EnteredContext, so that MicrotaskContext can nest. Here is a brief explanation: https://docs.google.com/document/d/1MY_xlsYS7E6_qbwwY66-FH3JkAYeTHBlF5qVBrBpWyY/edit Benchmark result: No significant performance difference is observed for this CL. See "patched" row for the result of this CL.

We assert that loops always have effect phis because there must be a stack check in every loop. However, with generators, the stack check may end up outside of loop because the dispatch switch is built first (while the dispatch switch will also keep the loop backedge alive). The logic for creating effect phis is already in the code, so removing the dcheck should be fine.

This change makes the SFI to bytecode link pseudo-weak. The marking visitors check whether the bytecode is old, and if so, don't mark it and instead push the SFI onto a bytecode_flushing_candidates worklist. Once marking is complete, this list is walked, and for any of the candidates who's bytecode has not been marked (i.e., is only referenced by the shared function info), the bytecode is flushed and the SFI has the function data replaced with an UncompiledData (which overwrites the flushed bytecode array). Since we don't track JSFunctions, these can still think the underlying function is compiled, and so calling them will invoke InterpreterEntryTrampoline. As such, logic is added to InterpreterEntryTrampoline to detect flushed functions, and enter CompileLazy instead.
