0.9.6.25:
	Have you ever tried jumping to the definition of a method combination
        with M-. only to be thwarted by Slime/SBCL? Yeah, me neither...

	* Record source location information for all definition forms.
          (Except when (AND (> SPACE DEBUG) (> SPACE 1))).
        * On by default, can be disabled by removing :SB-SOURCE-LOCATIONS
          from build-features (if you really want to save that last 60kB
          of space...)
        * Add structure SB-C:DEFINITION-SOURCE-LOCATION for saving the
          source locations
        * Annotate all definition form macros with calls to
          SB-C:SOURCE-LOCATION, which is compiler-macro-expanded
          to a D-S-L instance and saved into an appropriate place.
        * For cases where no appropriate place exists, add new
          info class :SOURCE-LOCATION.
        * Some trickery required to get the source locations recorded
          for early definitions.
        * SB-INTROSPECT:FIND-DEFINITION-SOURCE no longer tries to guess
          what definition to search for when given a symbol. (I don't
          feel too bad about this, since the interface is explicitly
          not supported yet).
        * New function SB-INTROSPECT:FIND-DEFINITION-SOURCES-BY-NAME
          for querying, e.g (FIND-DEFINITION-SOURCES-BY-NAME '*FOO* :VARIABLE).
          Returns a list of locations (to support things like
          (F-D-S-B-N 'FOO :METHOD) or (F-D-S-B-N 'foo :VOP)).
        * Stalate the fasls.
