sbc: ARMv6 optimized version of analysis filter for SBC encoder
The optimized filter gets enabled when the code is compiled
with -mcpu=/-march options set to target the processors which
support ARMv6 instructions. This code is also disabled when
NEON is used (which is a lot better alternative). For additional
safety ARM EABI is required and thumb mode should not be used.
Benchmarks from ARM11:
