Thanks, committed:

        Patch by: René Stadler <mail at renestadler dot de>

        * gst/replaygain/rganalysis.c: (yule_filter):
        Avoid slowdown from denormals when processing near-silence input data.
        Spotted by Gabriel Bouvigne. Fixes #494499.


PS: AFAIK one can set a FPU flag on x86 to treat denormals as zero. I'll
investigate and maybe we can use this in core somewhere to prevent things like
this.
