The {last_end_found_} field is redundant. If it's false, there will be a control struct left on the stack. Thus remove that field, and simplify the error detection condition.

`memory.init` copies bytes from a passive data segment to linear memory. `memory.drop` is an instruction that informs the wasm VM that the instance no longer needs access to the passive data segment. Information about the passive data segments, including their contents, length, and whether they are dropped, is stored in the `WasmInstanceObject` as primitive arrays.

There's no reason to restrict off-heap targets to builtin host Code objects during serialization. They can also occur e.g. in irregexp code created by embedded scripts.

InternalPackedArray now only has one constructor variant that expects no arguments (Chrome's only usage of InternalPackedArray). As such, these TFC builtins are no longer used and were removed: - InternalArrayNoArgumentConstructor_Holey - InternalArraySingleArgumentConstructor_Packed - InternalArraySingleArgumentConstructor_Holey On x64.release, this reduces builtins size by ~1.2KB.

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.

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.
