Optimizations to preprocessor's find_define(). - don't check for __FILE__ and __LINE__ until after we've checked our hash, since this is the less likely case. - Check against the hard-coded hash value of the strings "__FILE__" and "__LINE__" to avoid unnecessary strcmp() calls. This dropped the profile of this function from 20% of our total CPU time to 10%. Of that 10%, 70% is now the hashing function.


# !!! FIXME: use this to correct our estimates some day.
