3f686f6a7d avcodec/g729postfilter: Clip gain before scaling with AGC_FAC1 
The fixed point integer reference specifies the multiplication used
to have 16bit input and clips so we need to clip the input
The floating point implementation does not seem to do that.

Alternatively the arrays can be made bigger or the index can be clipped.
In case a real file with such huge tiles exist we ask the user to upload it.
