Bug 1671228 is adding GuardMultipleShapes as part of stub folding. Jan pointed out in review that instead of unboxing each element of the list of expected shapes and comparing it against the object's shape, we could box the object's shape once and compare boxed values.

I was already staring at register allocation in this function, so it seemed like a reasonable time to fix this.
Depends on D163154
