Nicolai Haehnle 5dea645138 AMDGPU: Move v_readlane lane select from VGPR to SGPR
Summary:
Fix a compiler bug when the lane select happens to end up in a VGPR.

Clarify the semantic of the corresponding intrinsic to be that of
the corresponding GLSL: the lane select must be uniform across a
wave front, otherwise results are undefined.
