I did builds for x86_64 and arm (USE_CELT_FIR on and off, -O0, -O2,
gcc & clang) that checked for new warnings / c90 compatibility. The
optimized arm gcc builds (with --enable-check-asm) were used to check
bit exactness for complexity 0-10 at 8, 16, 48kHz using a few sample
rtc clips. ASan/UBSan builds pass as well.
I also made a pass through the NEON before this was forwarded, it
looks in line with the C.
