avcodec/acelp_pitch_delay: Inline small functions only used once
ff_acelp_decode_8bit_to_1st_delay3, ff_acelp_decode_4bit_to_2nd_delay3
and ff_acelp_decode_5_6_bit_to_2nd_delay3 are all only used once (by
g729dec) whereas ff_acelp_decode_9bit_to_1st_delay6 and
ff_acelp_decode_6bit_to_2nd_delay6 are completely unused; with the
possible exception of ff_acelp_decode_4bit_to_2nd_delay3, these
functions are so small that inlining them is appropriate; and as long as
ff_acelp_decode_4bit_to_2nd_delay3 is only called once, this is also
true for it.
