bug#451: 23.0.60; x-gtk-map-stock destroys match data

[Nick Roberts <nickrob@snap.net.nz>]

In the event loop (?), update_frame_tool_bar calls x-gtk-map-stock (in
x-win.el) which uses string-match.  This changes the match data that I need for
my application.  I don't know what the rules are about using string-match from
C code but as a minimum x-gtk-map-stock should wrap save-match-data around
the call to it.
