This adds a ir_variable which contains the subroutine uniform
and an array rvalue for the deref of that uniform, these
are stored in the ir_call and lowered later.

We need to store two sets of info into the ir_function,
if this is a function definition with a subroutine list
(subroutine_def) or if it a subroutine prototype.
v1.1: add some more documentation.

This type will be used to store the name of subroutine types
as in subroutine void myfunc(void);
will store myfunc into a subroutine type.
This is required to the parser can identify a subroutine
type in a uniform decleration as a valid type, and also for
looking up the type later.
Also add contains_subroutine method.
v2: handle subroutine to int comparisons, needed
for lowering pass.
v3: do subroutine to int with it's own IR
operation to avoid hacking on asserts (Kayden)

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.

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.
