Revert of [turbofan] ChangeFloat64ToTagged shouldn't canonicalize. (patchset #6 id:100001 of https://codereview.chromium.org/2367593003/ ) Reason for revert: Still blows up on the main waterfall even after Jakob's fix: https://build.chromium.org/p/client.v8/builders/V8%20Mac64/builds/11557/steps/Check/logs/typedarray-indexing https://build.chromium.org/p/client.v8/builders/V8%20Mac64/builds/11557/steps/Check/logs/typedarray https://build.chromium.org/p/client.v8/builders/V8%20Win64/builds/12982/steps/Check/logs/typedarray Original issue's description: > [turbofan] ChangeFloat64ToTagged shouldn't canonicalize. > > This matches current Crankshaft/fullcodegen behavior more closely and > thus reduces the chances that we run into unnecessary polymorphism due > to the field representation tracking in our object model. > > R=jarin@chromium.org > BUG=v8:5267 > > Committed: https://chromium.googlesource.com/v8/v8/+/6a939714e991ebf10d56ddbd2869325cca99c0ef > Committed: https://crrev.com/ee158e6c4cc896479a32245432a3c2fdd31bcb73 > Committed: https://crrev.com/ddf792beb3a72f6dba83e94fc8ada03ebf1630bd > Cr-Original-Commit-Position: refs/heads/master@{#39692} > Cr-Commit-Position: refs/heads/master@{#39748} TBR=jarin@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
