(gdb-tooltip-print-1): Fix regexp.

(gdb-registers-font-lock-keywords): Delete.
(gdb-registers-mode): Don't fontify.
(gdb-info-registers-custom): Use text properties instead as, in
future, changed register values will use font-lock-warning-face.
(gdb-local-font-lock-keywords): Rename to...
(gdb-locals-font-lock-keywords): ...for consistency.
