Ian Romanick 11c6b6c102 intel/elk: Remove dsign optimization ... This bit from the comment should have been a big red flag: There are currently zero instances of fsign(double(x))*IMM in shader-db or any test suite, so it is hard to care at this time. The implementation of that path was incorrect. The XOR instructions should be predicated like the OR instruction in the non-multiplication path. As a result, dsign(zero_value) * x will not produce the correct result. Instead of fixing this code that is never exercised by anything, replace it with the simple lowering in NIR. Ironically, the vec4 implementation is correct. The odds of encountering an application that is performace limited by dsign performance in vertex processing stages on Ivy Bridge or Haswell is infinitesimal. No shader-db changes on any Intel platform. v2: Delete 's' in emit_fsign as it is now unused.
