What is EXTBF? Extract byte to float?
I ask because Unigine Heaven has shaders that pack 3x byte-integers

Some Unigine shaders have been observed to unpack bytes out of 32-bit
integers and convert them to floats. I2F/I2I can handle this sort of
thing directly. Detect the handleable situations.
This misses 16-bit word capabilities in nv50, but I haven't seen shaders
that would actually make use of

Probable duplicate bug (though this current bug was filed earlier) with more

I was able to initiate an apitrace when some textual corruptions (but not the
full menu corruptions which happen in the later stages) started appearing on
the plasmashell menus.

Probably the same bug responsible:
https://bugs.freedesktop.org/show_bug.cgi?id=91125 includes screenshots of
corruption from another user.
