[turbofan] Remove minus zero check for rhs of CheckedInt32Sub. The only way to get a minus zero result from subtraction is (-0) - (+0) = -0, hence checking for minus zero on the RHS is redundant. This is causing some unnecessary deoptimisations in Box2D from Octane on 32-bit platforms. BUG= Review-Url: https://codereview.chromium.org/2410883003 Cr-Commit-Position: refs/heads/master@{#40207}
