tests/checkasm: Add snowdsp test
Only inner_add_yblock for now.
Hint: Said function uses a pointer to an array of pointers as parameter.
The MMX version clobbers the array in such a way that calling the
function repeatedly with the same arguments (as happens inside bench_new())
leads to buffer overflows and segfaults. Therefore CALL4 had to be
overridden to restore the original pointers. This workaround will be
removed soon when the MMX version is removed.
