[Mesa-dev] [PATCH 01/27] gallium/radeon: expose LLVM functions implementing emit_store

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

emit_store will be reimplemented for tessellation control shader outputs
where only radeon_llvm_saturate will be used, but radeonsi will want to
fall back to radeon_llvm_emit_store for other register types.

This exposes both functions.
