Details

According to callgring on 64-bit Linux js_AtomizeString takes about 2-3% of browser startup time. Part of that time is spend on atomizing string literals embedded into the script. If these literals are not used to access properties such initial atomization is useless and just adds to the parse time. So the idea is to investigate how often we do this useless atomizations. If it takes substantial time, we should consider doing atomizations only for names.
