In the Crankshaft days we (mis)used the Representation to also express the various internal representations that the compiler understands. But with TurboFan we now have proper MachineRepresentation and MachineType, which do that independently. So there's no need to have this in the Representation class anymore, and instead the Representation class only needs to deal with the field representations. Bug: v8:8749, v8:8834, v8:8865 Change-Id: I34ea9558b5fdf20d6c7939b52762eaffd4316b06 Reviewed-on: https://chromium-review.googlesource.com/c/1479954 Commit-Queue: Benedikt Meurer <bmeurer@chromium.org> Reviewed-by: Jaroslav Sevcik <jarin@chromium.org> Cr-Commit-Position: refs/heads/master@{#59750}
