Due to inlining and enabled optimization the compiler will not create
machine instructions for the if-clauses and left shift for
sample_move_dS_s32s() and sample_move_dS_s32().

Due to the optimization of the compiler this commit does not introduce any
differences in the machine instructions.
Tested with GCC version 6.2.0 on ARM64 and x86_64.

ALSA expects right-aligned samples (0x00******) as mentioned in the
source code for SND_PCM_FORMAT_S24_LE:
Signed 24 bit Little Endian using low three bytes in 32-bit word

GCC defines __ARM_NEON__ for asimd on ARMv7 and __ARM_NEON for simd on
ARMv8. Therefore also check for __ARM_NEON.
