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

Array.indexOf accepts an optional fromIndex argument. When non-negative,
this argument restricts the searched indices to those starting at
fromIndex:
[1, 2, 1].indexOf(1,1) == 2
When negative, it is meant to be added to the array length to provide
such initial index for the search:
[1, 2, 1].indexOf(1, -2) == 2
This transformation has been done by the non-optimised builtin but not
by the reducer. The CL adds this construction to the reducer.
