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.
