[COMMITTED 2/3] i386.cc: Add override keyword where it is missing

[Filip Kastl]

Clang produces -Winconsistent-missing-override for a member function
in i386.cc.  This patch adds the override keyword for this function.
This has no effect on functionality.

Pushed as obvious.

gcc/ChangeLog:

        * config/i386/i386.cc: Add a missing override keyword for a
        member functions.
