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

In the recent port of reduce() and reduceRight(), a check for a length
change during the loop (standard for iterating builtins) was omitted.
We did get array bounds check protection, however it didn't expose
the issue in our tests because the bounds check is against the
backing store length, not against the length in the referring JSArray.
Also added a test for reduceRight().

Given that the index we use is checked to be in array index range there is no
need for a costly ToString conversion. All involved helpers for lookup up
properties directly support Smi/HeapNumber indices directly.
Cleanup: Rename GotoUnlessNumberLessThan => GotoIfNumberGreaterThanOrEqual

Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:
try {
shouldThrow();
assertUnreachable();
} catch(e) {
}
Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.
