      [turbofan] Add early detection of object state cycles. · 59a38a9a
      mstarzinger authored 
      This makes sure cycles in the object states graph are detected early by
escape analysis instead of late in the scheduler. This is mainly done
for improved debuggability.

      Revert of [Interpreter] Optimize BytecodeArrayBuilder and BytecodeArrayWriter. (patchset #6 id:200001 of https://codereview.chromium.org/2351763002/ )

Reason for revert:
Prime suspect for roll blocker: https://codereview.chromium.org/2362503002/

Original issue's description:
> [Interpreter] Optimize BytecodeArrayBuilder and BytecodeArrayWriter.
>
> This CL optimizes the code in BytecodeArrayBuilder and
> BytecodeArrayWriter by making the following main changes:
>
>  - Move operand scale calculation out of BytecodeArrayWriter to the
> BytecodeNode constructor, where the decision on which operands are
> scalable can generally be statically decided by the compiler.
>  - Move the maximum register calculation out of BytecodeArrayWriter
> and into BytecodeRegisterOptimizer (which is the only place outside
> BytecodeGenerator which updates which registers are used). This
> avoids the BytecodeArrayWriter needing to know the operand types
> of a node as it writes it.
>  - Modify EmitBytecodes to use individual push_backs rather than
> building a buffer and calling insert, since this turns out to be faster.
>  - Initialize BytecodeArrayWriter's bytecode vector by reserving 512
> bytes,
>  - Make common functions in Bytecodes constexpr so that they
> can be statically calculated by the compiler.
>  - Move common functions and constructors in Bytecodes and
> BytecodeNode to the header so that they can be inlined.
>  - Change large static switch statements in Bytecodes to const array
> lookups, and move to the header to allow inlining.
>
> I also took the opportunity to remove a number of unused helper
> functions, and rework some others for consistency.
>
> This reduces the percentage of time spent in making BytecodeArrays
>  in  CodeLoad from ~15% to ~11% according to perf. The
> CoadLoad score increase by around 2%.
