31c6f6f65c fmtconvert: Add a new method, int32_to_float_fmul_array8
This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).

94ee7da08d Remove pointless av_cold attributes in header files
The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.

d21be5f15b cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec().
It only has Altivec functions and is not compiled if Altivec is disabled.

c73d99e672 Separate format conversion DSP functions from DSPContext.
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.
