[9fans] 6a bug

[erik quanstrom]

i plan to look at this when i get home, but it appears that 6a
doesn't like big numbers.  demo script follows

- erik
-------
; cat >a.s <<'EOF'
#define KZERO   (0xffffff0000000000ull)

TEXT bignumber(SB), 1, $0
        ADDQ    $KZERO, AX
        RET
EOF
; cat >ac.c<<EOF
#include <u.h>
#include <libc.h>

extern uvlong bignumber(uvlong);

void
main(void)
{
        print("%llux\n", bignumber(0));
        exits("");
}
EOF
; 6a a.s; 6c ac.c; 6l a.6 ac.6
