test(agc): enter whole quad mode in the implicit-LOD 1D sample test

A pixel wave starts with only its covered pixels in EXEC, so a shader that
takes an implicit LOD has to run s_wqm first or the helper lanes of a partly
covered quad hold no coordinate. The test's pixel shader did not, which goes
unnoticed while its one triangle covers every quad whole. llvmpipe clips that
triangle at twice the viewport into three, and in the quads on the two inner
edges the helpers' zero coordinate gave the last mip instead of the expected
one.

The shader now starts with s_wqm_b64 exec, exec, as a compiled pixel shader
that samples with an implicit LOD does.
