util: return 0 for NaNs in float_to_ubyte

d3d10 requires NaNs to get converted to 0 for float->unorm conversions
(and float->int etc.). GL spec probably doesn't care in general, but it
would make sense to have reasonable behavior in any case imho - the
old code was converting negative NaNs to 0, and positive NaNs to 255.
(Note that using float comparison isn't actually all that much more
effort in any case, at least with sse2 it's just float comparison
(ucommiss) instead of int one - I converted the second comparison
to float too simply because it saves the probably somewhat expensive
transfer of the float from simd to int domain (with sse2 via stack),
so the generated code actually has 2 less instructions, although float
comparisons are more expensive than int ones.)

https://android.googlesource.com/platform/external/mesa3d/+/bd633f11de0c6ac1ed333a28344c74fd9898df9e%5E%21/

Which replaces HOST_OUT_release with HOST_OUT

As per Dan's explanation, the current code was incorrect to use
$(HOST_OUT_release) as $(HOST_OUT) will be set properly for
whether the current build that's being cleaned during
incrementals is using host debug or release builds.

Additionally Dan noted it was incredibly uncommon to use a debug
host build, as there was never a shortcut and one had to set an
environment variable manually. Thus it was rarely if ever tested.
