Add support for the subroutine uniform type ir->mesa.cpp
v1.1: add subroutine to int to switch

This fleshes out the ARB_program_query support for the
APIs that ARB_shader_subroutine introduces, leaving
some TODOs for later addition.
v2: reworked for lots of the ARB_program_interface_query
entry points and tests
v3: use common function to test for subroutine support
v3.1: add tess, fix missing breaks

This adds linker support for subroutine uniforms, they
have some subtle differences from real uniforms, we also hide
them and they are given internal uniform names.
This also adds the subroutine locations and subroutine uniforms
to the program resource tracking for later use.
v1.1: drop is_subroutine_def
v2: handle explicit location properly, ARB_explicit_location
has a lot of language for subroutine shaders.
Calculate a link time the number of compatible subroutines
for a uniform, to make program resource easier later.

This adds the necessary storage for subroutine info to gl_shader.

This lowers the enhanced ir_call using the lookaside table
of subroutines into an if ladder. This initially was done
at the AST level but it caused some ordering issues so a separate
pass was required.
v2: clone return value derefs.
v2.1: update for subroutine->int convert.
v2.2: add a clone for the array index

This is the guts of the GLSL parser and AST support for
shader subroutines.
The code creates a subroutine type in the parser, and
uses that there to validate the identifiers. The parser
also distinguishes between subroutine types/function prototypes
/uniforms and subroutine defintions for functions.
Then in the AST conversion it recreates the types, and
stores the subroutine definition info or subroutine info
into the ir_function along with a side lookup table in
the parser state. It also converts subroutine calls into
the enhanced ir_call.
v2: move to handling method calls in
function handling not in field selection.
v3: merge Chris's previous parser patches in here, to
make it clearer what's changed in one place.
v3.1: add more documentation, drop unused include
v3.2: drop is_subroutine_def

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.
