3ce91c727f radeonsi: rework how shader pointers to descriptors are set 
This is mainly needed for tessellation where a VS can be bound as VS, ES,
or LS, and TES (tess. evaluationshader) can be bound as VS or ES or neither.
Therefore we need the ability to move pointers to descriptors between
shaders arbitrarily.

The idea is that the context has a mapping from PIPE_SHADER_x to
SPI_SHADER_USER_DATA_x. After a shader is enabled or disabled,
si_shader_change_notify should be called to update this mapping accordingly.

There is a dirty flag for each shader pointer, but only one emit function
for all pointers in the whole context, whose code and logic is separated
from descriptors.

a3be59b4a9 gallium/radeon: expose LLVM functions implementing emit_store 
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.
