tests: Add remap test code to cpu-test
v2 (comments by Paul Menzel): * generate test samples from -1..1, -0x8000..0x7fff * check all output samples (not just half of them) the idea is to compare the output of the C (reference) implementation against the output of the optimized code path; currently, there are MMX and SSE implementation for the mono-to-stereo remapper for s16 and float sample formats Signed-off-by: Peter Meerwald <p.meerwald@bct-electronic.com> Cc: Paul Menzel <paulepanter@users.sourceforge.net>
