From the GL 4.6 spec: "If the value of any non-ignored component of the offset vector operand is outside implementation-dependent limits, the results of the texture lookup are undefined." We shouldn't assertion fail, then. GLSL-to-NIR shouldn't be enforcing limits on TG4 offsets, since it doesn't for non-TG4 tex_src_offset either. Leave it up to the driver to handle it. Fixes a crash in a piglit test on nouveau that supplies a negative random number up to 10,000 as the first coordinate for some reason. Other NIR drivers lowered TG4 explicit offsets to tex_src_offset, so they weren't affected.
