Found with IWYU, confirmed with grepping for "hash" and "symbol".
No negative effects on compilation.
IWYU also reported core.h and linker.h could be removed,
but I'm unsure if those are false positives.

Previously, a UBO like
layout(binding=2) uniform U {

wouldn't get any bindings set. The code would try to set the binding of
U, but that would fail. It should instead set the bindings for U[0],
U[1], ...

For blocks, gl_shader_program::UniformStorage isn't very useful. The
names stored there are the names of the elements of the block, so
finding blocks with an instance name is hard. There is also only one
entry in ::UniformStorage for each element of a block array, and that is
a deal breaker.
Using ::UniformBlocks is what _mesa_GetUniformBlockIndex does. I
contemplated sharing code between set_block_binding and
_mesa_GetUniformBlockIndex, but building the stand-alone compiler and
the unit tests make this hard. I plan to return to this effort shortly.

In the next patch, we'll see that using
gl_shader_program::UniformStorage is not correct for uniform blocks.
That means we can't use ::UniformStorage to select between the sampler
path and the block path. Instead we want to just use the type of the
variable. That's never passed to set_uniform_binding, and it's easier
to just remove the function (especially for later patches in the series)
than to add another parameter.

samplers
The two code paths are quite different, and there are some problems in
the handling of uniform blocks. Future changes will cause these paths
to diverge further. Ultimately, selecting between the two functions
will happen at the set_uniform_binding call site, and
set_uniform_binding will be deleted.
NOTE: This patch just moves code around.

Previously, we had an enum called gl_shader_type which represented
pipeline stages in the order they occur in the pipeline
(i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several
inconsistently named functions for converting between it and other
representations:
- _mesa_shader_type_to_string: gl_shader_type -> string
- _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type
- _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type
- _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
This patch tries to clean things up so that we use more consistent
terminology: the enum is now called gl_shader_stage (to emphasize that
it is in the order of pipeline stages), and the conversion functions are:
- _mesa_shader_stage_to_string: gl_shader_stage -> string
- _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage
- _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage
- _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES,
for consistency with the new name for the enum.

layout(binding = N) is equivalent to calling glUniformBlockBinding(_,N).
This currently only handles the GLSL 1.40 case - no interface names, no
arrays of uniform blocks. This is okay since we don't yet support GLSL
1.50, and don't expose ARB_shading_language_420pack in ES 3.0.
v2: Move into the other function; use binding, not constant_value.

Normally, uniform array variables are initialized by array literals.
That is, val->type->array_elements >= storage->array_elements.
However, samplers are different. Consider a declaration such as:
layout(binding = 5) uniform sampler2D[3];
The initializer value is a single integer (5), while the storage has 3
array elements. The proper behavior here is to increment one for each
element; they should be initialized to 5, 6, and 7.
This patch introduces new code for sampler types which handles both
arrays of samplers and single samplers correctly.
v2: Move into the other function; use binding, not constant_value.

Sampler uniforms and uniform blocks do not have a var->constant_value.
Instead, they have an integer var->binding value.
This makes extending set_uniform_initializer() somewhat problematic: it
assumes that there is an ir_constant * which represents the initializer,
and that it's safe to dereference that without any NULL checks.
Instead, this patch creates an analogous function for binding
qualifiers, and calls one or the other as appropriate.

There is existing code to handle sampler uniform initializers. Prior to
GLSL 4.20's "binding" keyword, sampler uniforms don't have initializers
at all, so this is somewhat surprising.
The existing code is broken into two cases: one where both the variable and
initializer are arrays, and a second where the variable and initializer are
scalars.
The first case should never occur, since array-typed initializers do not
exist for sampler uniforms. Even with the binding keyword, the
initializer is a single integer which represents the texture unit to use
for the first array element.
The second is apparently used for some fixed-function code.
v2: Rewrite the commit message - suggested by Paul.

The problem is the sampler units are allocated from the same pool for all
shader stages, so if a vertex shader uses 12 samplers (0..11), the fragment
shader samplers start at index 12, leaving only 4 sampler units
for the fragment shader. The main cause is probably the fact that samplers
(texture unit -> sampler unit mapping, etc.) are tracked globally
for an entire program object.
This commit adapts the GLSL linker and core Mesa such that the sampler units
are assigned to sampler uniforms for each shader stage separately
(if a sampler uniform is used in all shader stages, it may occupy a different
sampler unit in each, and vice versa, an i-th sampler unit may refer to
a different sampler uniform in each shader stage), and the sampler-specific
variables are moved from gl_shader_program to gl_shader.
This doesn't require any driver changes, and it fixes piglit/max-samplers
for gallium and classic swrast. It also works with any number of shader
stages.
v2: - converted tabs to spaces
- added an assertion to _mesa_get_sampler_uniform_value

Interfaces are structurally identical to structures from the compiler's
point of view. They have some additional restrictions, and generally
GPUs use different instructions to access them. Using a different base
type should make this a bit easier.
This commit also adds the glsl_type::interface_packing fields. For
GLSL_TYPE_INTERFACE types, this will track the specified packing mode.
It is analogous to gl_uniform_buffer::_Packing.
v2: Add serveral missing GLSL_TYPE_INTERFACE cases in switch-statements.
v3: Add information about glsl_type::interface_packing. Move row_major
checking in glsl_type::record_key_compare from this patch to the
previous patch. Both suggested by Paul Berry.

This makes it easier to find switch-statements that need to be updated
after a new GLSL_TYPE_* is added because the compiler will generate a
warning.
Switch-statements that only had a small number of cases (e.g.,
everything in ir_constant_expression.cpp) were not modified. I may
regret that decision when we eventually add support for doubles.
