avcodec/dirac_arith: Fix build with PIC and stack-check options
Fixes Ticket3540 The function dirac_get_arith_bit in libavcodec/dirac_arith.h can't be built with PIC and check-stack because the asm code needs 6 registers and PIC and check-stack options take 1 each and x86 is quite limited in this area. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
