Decrease string allocations in url_options
The request.script_name is dup-d which allocates an extra string. It is most commonly an empty string "". We can save a ton of string allocations by checking first if the string is empty, if so we can use a frozen empty string instead of duplicating an empty string.
This change buys us 35,714 bytes of memory and 893 fewer objects per request.
