838a6871bb glsl: Convert piles of foreach_iter to foreach_list_safe.
In these cases, we edit the list (or at least might be), so we use the
foreach_list_safe variant.

88ee9bc9d1 glsl: Add support for specifying the component in textureGather
ARB_gpu_shader5 introduces new variants of textureGather* which have an
explicit component selector, rather than relying purely on the sampler's
swizzle state.

This patch adds the GLSL plumbing for the extra parameter.

426ca34b7a glsl: Remove ir_print_visitor.h includes and usage
We have ir->print() to do the old declaration of a visitor and having the
IR accept the visitor (yuck!).  And now you can call _mesa_print_ir()
safely anywhere that you know what an ir_instruction is.

A couple of missing printf("\n")s are added in error paths -- when an
expression is handed to the visitor, it doesn't print '\n' (since it might
be a step in printing a whole expression tree).

110ca8b1f3 glsl: Implement ARB_texture_query_lod
v2 [mattst88]:
   - Rebase.
   - #define GL_ARB_texture_query_lod to 1.
   - Remove comma after ir_lod in ir.h for MSVC.
   - Handled ir_lod in ir_hv_accept.cpp, ir_rvalue_visitor.cpp,
     opt_tree_grafting.cpp.
   - Rename textureQueryLOD to textureQueryLod, see
     https://www.khronos.org/bugzilla/show_bug.cgi?id=821
   - Fix ir_reader of (lod ...).
v3 [mattst88]:
   - Rename textureQueryLod to textureQueryLOD, pending resolution of
     Khronos 821.
   - Add ir_lod case to ir_to_mesa.cpp.

ffb53b4f03 glsl: add support for ARB_texture_multisample
V2: - emit `sample` parameter properly for multisample texelFetch()
    - fix spurious whitespace change
    - introduce a new opcode ir_txf_ms rather than overloading the
      existing ir_txf further. This makes doing the right thing in
      the driver somewhat simpler.

V3: - fix weird whitespace

V4: - don't forget to include the new opcode in tex_opcode_strs[]
      (thanks Kenneth for spotting this)

8c2a983835 glsl: Add a variant of the rvalue visitor for handle_rvalue() on the way down.
For the UBO lowering pass, I want to see the whole dereference chain for
replacing, not the innermost ir_dereference_variable.

c5a27b5939 glsl: Change texel offsets to a single vector rvalue.
Having these as actual integer values makes it difficult to implement
the texture*Offset built-in functions, since the offset is actually a
function parameter (which doesn't have a constant value).

The original rationale was that some hardware needs these offset baked
into the instruction opcode.  However, at least i965 should be able to
support non-constant offsets.  Others should be able to rely on inlining
and constant propagation.
