For all of the OpFOrd* comparisons except OpFOrdNotEqual the hardware

the sign is the same but both numbers are sufficiently small
(if the product is smaller than 2^-128).
This could apparently lead to emitting a sufficient amount of

hitting an assertion (still safe with release builds since we just

Not sure if the additional vertices could cause other grief, I didn't
see anything wrong even when hitting the assertion.

Essentially, both +-0 are treated as positive (the vertex is considered

i965/meta_util: Re-enable sRGB-encoded fast-clears on CNL

The paths which sample with the clear color are now using a getter which
performs the sRGB decode needed to enable this fast clear.

This path can be exercised by fast-clearing a texture, then performing
an operation which requires sRGB decoding. Test coverage for this
feature is provided with the following tests:

* Shader texture calls:
  - spec@ext_texture_srgb@tex-srgb

* Shader texelfetch calls:
