compiler: Move t_type::generate_fingerprint to a .cc file

Forcing all of the functions under src/parse to be defined in header
files is silly and sometimes painful.  Createa a "parse.cc" file for
functions that don't belong in header files.  To start, move
generate_fingerprint there, because it requires including md5.h.
