ThrowIfHole bytecodes were handled by introducing deopt points to check
for a hole. To avoid deopt loops a hole check protector was used to
generate control flow if there was a deopt due to a hole. However, the
normal control flow version should be as fast as the deopt version
in general. The deopt version could potentially consume less compile time
but it may not be worth the complexity added. Hence simplifying it to
only construct the control flow.

The two variants "turbofan" and "turbofan_opt" are not part of any of

This CL contains a few pieces:

- A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan
  graphs, which--when triggered--swizzle the values in the the FrameState to be
  parameters to a typically TF-generated builtin that resumes execution to finish
  the slow-case functionality.
- Continuation builtins that have special handling in the deoptimizer and their own
  new frame type to ensure that the values they need to begin executing can be stashed
  away and restored immediately before the builtin is called via a trampoline that runs
  when the continuation builtin's frame execution resumes.
- An implementation of Array.prototype.forEach in TurboFan that can be used to
  inline it. The inlined forEach implementation uses the checkpoints mechanism
  described above to deopt in the middle of the forEach in the cases that optimization
  invariants are violated. There is a slightly different continuation stub for each
  deopt point in the forEach implementation to ensure the correct side-effects, i.e.
  that the deopt of the builtin isn't programmatically observable.

updates the WebAssembly spec tests. The WebAssembly spec tests have to
be updated manually with the tools/wasm/update-wasm-spec-tests.sh

UPDATE: I improved the update script slightly, and there is one

deprecating the old pipeline, the added complexity introduced by code
flushing is no longer worth it. This CL removes it (but keeps code aging,
which is used to unlink SFIs from the compilation cache).
