glsl: Add infrastructure for "hidden" uniforms.

2014-11-07T00:20:01+00:00

In the compiler, we'd like to generate implicit uniforms for internal
use.  These should not be visible via the GL uniform introspection API.

To support that, we add a new ir_variable::how_declared value of
ir_var_hidden, and plumb that through to gl_uniform_storage.

v2 (idr): Fix some memory management issues in
move_hidden_uniforms_to_end.  The comment block on the function has more
details.

glsl: Remove now useless dot optimization on basis vect

2014-11-03T19:27:50+00:00

The optimization in commit d056863b covers these cases, which were the
first optimizations I added to the GLSL compiler.

glsl: Squish ir_variable::max_ifc_array_access and ::state_slots together

2014-09-30T20:34:42+00:00

At least one of these pointers must be NULL, and we can determine which
will be NULL by looking at other fields.  Use this information to store
both pointers in the same location.

If anyone can think of a better name for the union than "u", I'm all
ears.
