Remove "struct" from foreach statements

Some versions of gcc have a bug that causes

    for (struct mumble : something)

... to give a compiler error.  We routinely work around this bug in
gdb, but apparently had not done so in a while.  This patch fixes the
remaining known cases of this problem.
