x86: adjust st(<N>) parsing
st(1) ... st(7) will never be looked up in the hash table, so there's no point inserting the entries. It's also not really necessary to do a 2nd hash lookup after parsing the register number, nor is there a real reason for having both st and st(0) entries. Plus we can easily do away with the need for st to be first in the table.
