        Misc.

	* Support SETF function names in SB-INTROSPECT:FUNCTION-ARGLIST.
          (Patch by Todd Mokros on sbcl-devel)
        * Minor performance improvement in the x86-64 assembler. (Patch
          by Lutz Euler on sbcl-devel)
        * Add a recursive TRACE :ENCAPSULATE NIL (supposed to be part
          of a recent Solaris/x86 commit, but somehow didn't make it
          through)
        * Add a failing FILE-POSITION test on utf-8 streams. (Reported
          by Lutz Euler)
