With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

We need to rename the receiver on CheckHeapObject, because we
don't canonicalize numbers in SignedSmall range, and thus we
the representation selection can hand out TaggedSigned values
for receiver uses, even though we checked for TaggedPointerness
first.
Note that this is rather hacky and just intended to fix the bug
ASAP. We need to think about how to deal with representations in
earlier compilation stages.
