The biggest chunk of this CL is related to the CodeBuilder now returning a Code object instead of an InstructionStream. Most codegen-related parts of the codebase had to be updated, including compiler.cc, pipeline.cc, and many tests. The good news is, we now have 400 fewer references to InstructionStream. Smaller changes: - Remove ToAbstractCode - Remove dead code - Update comments - Update method and variable names Bug: v8:13654 Change-Id: Ieb12bc698af576e07016e4c5c8c9d494e5addb0e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/4174091 Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> Auto-Submit: Jakob Linke <jgruber@chromium.org> Commit-Queue: Adam Klein <adamk@chromium.org> Reviewed-by: Leszek Swirski <leszeks@chromium.org> Reviewed-by: Adam Klein <adamk@chromium.org> Cr-Commit-Position: refs/heads/main@{#85372}
