Sathya Gunasekaran 5c59ba4fbc [ic] Fix KeyedLoadIC for ArrayIndex access 
Previously, without support for converting strings to numbers we'd
switch to megamorphic state and go to the runtime always to do the
conversion causing a performance cliff.

This patch improves the following js-perf-test scores:
Object-Lookup-String-Constant-BytecodeHandler: 4.25%
Object-Lookup-Index-String-BytecodeHandler: 5.41%
