Make CELT FFT twiddle complex type aligned This makes kiss_twiddle_cpx 4-byte aligned (instead of 2-byte) for fixed-point builds. Tested with an armv6j+nofp development board, CELT encoding becomes 1.4x as fast, and decoding over 2x. Performance gain is mostly attributed to the proper alignment of the static const array mdct_twiddles960. Co-authored-by: David Gao <davidgao@google.com> Signed-off-by: Felicia Lim <flim@google.com>
