gallium/tgsi: add support for DEMOTE and READ_HELPER opcodes

This mirrors the intrinsics in the GLSL IR. One could imagine an
alternate definition where reading the semantic would account for the
READ_HELPER functionality, but that feels potentially dodgy and could be
subject to CSE unpleasantness.
