c883da6bf4 AAC encoder: fix signed integer overflow 
Clamp scalefactors by coef2minsf to avoid undefined behavior
caused by signed integer overflow. It also avoids clipping of
coefficients so it should avoid artifacts as well, on very
rare corner cases.

02172d93f6 Revert "aacenc: use av_clip() instead of av_clip() during quantization" 
This reverts commit c0918613a0ecaac6819409c64107583eebc0ccc2, since it
triggered a new assertion with gcc.
This bug definitely needs a true proper fix.

c0918613a0 aacenc: use av_clip() instead of av_clip() during quantization 
Seems like clang might be miscompiling it and causing a signed integer overflow,
making a FATE test fail.
Doesn't seem to affect performance, it only runs on the ESC codebook.
