Note, the other arm asm code is likely affected too and should be changed as well.

The bit_rate_value_minus1 and cpb_size_value_minus1 elements
allow a wider range than get_ue_golomb() supports.  This
adds a get_ue_golomb_long() function supporting up to 31
leading zeros, which is the maximum for these syntax
elements, and uses it in decode_hrd_parameters().

60% speedup (overall decoding time) at 2 threads, and another 60%
speedup at 4 threads.

~3.0-3.5x as fast as original C version, 1.6x as fast overall.

The intermediate buffer is always aligned.

The level_code expression includes a shift which is invalid in
those cases where the value is not used.  Moving the calculation
to the branch where the result is used avoids these.

These additions might overflow the signed range for large
input values.  Converting to unsigned before the addition
rather than after avoids such undefined behaviour.  The
result under normal two's complement wraparound remains
unchanged.
