commit 3b8bd8385a96685faeb26da60d9394feafb79907

    Fix ticket ##104: Source location for define-condition
    
    This is the patch from the ticket except that the boot file name has
    been changed to conform to the usual naming rules.
    
    To test it, try (c::info :source-location :class 'error). This should
    return something like
    
    #S(C::FILE-SOURCE-LOCATION :FORM-NUMBERS 52 :PATHNAME "target:code/error.lisp")
    
    Notes:
    * compiler/globaldb.lisp: New info-type source-location/class.  As
    class names can theoretically also be variable names it seemed
    reasonable to introduce this instead of using the existing
    source-location/defvar.
    
    * code/error.lisp (%compiler-define-condition): Take
    source-location as argument and store it in the infodb.
    (define-condition): Pass source-location along.
    
    * bootfiles/20e/boot-2014-06-1.lisp: New bootfile needed
    because error.lisp is compiled before globaldb.lisp.
