This ensures that there is only one entrance point from C++ to generated code, hence only one method has to be excluded from CFI. It also introduces type safety by only allowing the code to be called with the right arguments. This CL includes minor drive-by fixes in the tests, like removing unused dummy variables.

If there is no constructor or species updates on Array or TypedArrays, then skip lookups of constructor and species so that we can create a new typed array quickly.

This seems to be a merge error. The if moved down by a few lines and now actually implements the bounds check instead of bailing out. Taking it out revealed a bug where we were trying to access the lowest 8 bits on a register where this is not allowed on ia32, thus a few more changes were needed in this CL.

This fixes two issues with --trace-wasm-decoder and --trace-liftoff. First, cache state tracing in liftoff only makes sense together with --trace-wasm-decoder, so disable it otherwise. Second, we were sometimes hitting a DCHECK with --trace-wasm-decoder on functions which bailed out to Turbofan, since the bailout was resetting the end pointer of the decoder to the current pc.

GetProperty CSA implementation bailouts prototype lookup when the holder is a typed array, which is to handle integer indexed exotic cases. However, this strict condition made too much overheads for search of common names such as "constructor". This CL checks the first character of a name, and do not bailout if we are sure that the name cannot be a special index.

In order to remove the CALL_GENERATED_CODE macro, it helps a lot to unify the interfaces of the simulators and make the Call method variadic in the number of arguments. This CL does that for each simulator. A follow-up CL will then completely remove the CALL_GENERATED_CODE macro and replace uses with the (new) GeneratedCode wrapper.

And apply a minor change: the {end_offset} is currently always >= 1, and we sometimes use {end_offset - 1}. Change this to compute the {end_offset} to be one less than before, and use {Uint32LessThan} instead of {Uint32LessThanOrEqual}. This matches the documentation I added and makes reasoning about the correctness of the checks easier (at least for me).

For simplicity, we currently use the approach to do all computations and bounds checks on 32 bit values, and only convert to pointer size right before using the value as memory offset. Unfortunately, there are still cases left where we use 32-bit values for 64-bit operations, which can lead to subtle bugs. This CL hopefully fixes the last of these bugs.
