linker: Implement first bits of intrastage linking
...
This currently involves an ugly hack so that every link doesn't result
in all the built-in functions showing up as multiply defined. As soon
as the built-in functions are stored in a separate compilation unit,
ir_function_signature::is_built_in can be removed.

linker: Refactor cross_validate_uniforms into cross_validate_globals
...
The later, more generic function will be used in the intra-stage linker.

linker: Use bit-0 instead of VERT_BIT_GENERIC0
...
Uses of the bits for allocation are offset by 16, and
VERT_BIT_GENERIC0 already has the 16 offset. As a result, it was
preventing the wrong thing from being allocated.

glsl2: Allow a fragment shader to not write a color.
...
I can't find any text justifying this check, and it caused a
reasonable-looking shader in glsl-bug-22603 (which writes only
gl_FragDepth) to fail.

linker: Don't dynamically allocate slots for linked shaders
...
The can be at most one shader per stage. There are currently only two
stages. There is zero reason to dynamically size this array.

glsl2: Use Mesa's gl_shader_program instead of our own struct glsl_program.
...
This avoids more allocation and shuffling of data around.

glsl2: Move our data from a glsl_shader* on the side to the main gl_shader *.
...
This saves recompiling at link time. gl_shader->ir is made a pointer
so that we don't have to bring exec_list into mtypes.h.
