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)

Previously, we stored the GLSL language version in the
glsl_symbol_table struct. But this was unnecessary--all
glsl_symbol_table needs to know is whether functions and variables
have separate namespaces (they do in GLSL 1.10 only).

Adding this now makes it easier to develop and test GLES3 features, since we
can do initial development and testing using desktop GL. Later GLSL compiler
patches check for either ctx->Extensions.ARB_ES3_compatibility or
_mesa_is_gles3 to allow certain features (i.e., "#version 300 es").

This should help avoid confusion now that we're using the gl_api enum
to distinguishing between core and compatibility API's. The
corresponding enum value for core API's is API_OPENGL_CORE.

This takes advantage of the builtin compiler to generate IR into a
string, the same way we read GLSL for function prototypes for our
profiles.

The built-in subsystem uses "profiles," or GLSL shaders containing
prototypes for all built-ins supported within a particular language
version (or extension) and shader stage.
Since profiles were stage-specific, we had to cut and paste almost all
the prototypes between (e.g.) 110.vert and 110.frag. Naturally, this
led to sundry cut and paste bugs, where someone fixed an issue in .frag
but neglected to update .vert, or vice-versa. Geometry shaders would
have only made this worse.
This patch introduces support for a new '.glsl' profile suffix which
contains prototypes common to all shader stages. The existing '.frag'
and '.vert' profiles need only contain the few stage-specific built-ins.
Not only does this remove duplication, it makes built-in setup slightly
faster: we don't need to re-read the common prototypes and function
bodies for both the vertex and fragment shader stage.
Internally, this was trivial. We already create a list of gl_shader
objects to search through for built-ins: one for the core language
version/stage, and additional shaders for any extensions in use. This
patch simply adds another shader to the list: core/common, core/stage,
and extensions.
The next patch will update the profiles to remove the duplication.
It's separated out purely to make review easier.

The builtins we have are generally optimized, having been
hand-written. This avoids generating bad code when an optimization
pass prints debug output.

This patch adds the extension '.ir' to all the files in
src/glsl/builtins/ir/, and changes generate_builtins.py so that it no
longer globs on '*' to find the files to build. This prevents
spurious files (such as EMACS' infamous *~ backup files) from breaking
the build.

Very simple shaders don't actually use GLSL built-ins. For example:
- gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
- gl_FragColor = vec4(0.0);
Both of the shaders used by _mesa_meta_glsl_Clear() also qualify.
By waiting to initialize the built-ins until the first time we need to
look for a signature, we can avoid the overhead entirely in these cases.
Makes piglit run roughly 18% faster (255 vs. 312 seconds).

I think was used long ago, when we actually read the builtins into the
shader's instruction stream directly, rather than creating a separate
shader and linking the two. It doesn't seem to serve any purpose now.

This makes a very simple 1.30 shader go from 196k of memory to 9k.
NOTE: This -may- be a candidate for the 7.9 branch, as the benefit is
substantial. However, it's not a simple change, so it may be wiser to
wait for 7.10.

This works around MSVC's 65535 byte limit, unfortunately at the expense
of any semblance of readability and much larger file size. Hopefully I

When releasing the builtin functions, we were just freeing the memory,

As of 1.20, variable names, function names, and structure type names all
share a single namespace, and should conflict with one another in the
same scope, or hide each other in nested scopes.
However, in 1.10, variables and functions can share the same name in the
same scope. Structure types, however, conflict with/hide both.
Fixes piglit tests redeclaration-06.vert, redeclaration-11.vert,
redeclaration-19.vert, and struct-05.vert.

This should make it easier to diff the output, clean up some of the
insane whitespace, and make the strings a bit smaller.
We'll probably need to split up the prototype strings eventually, but
for now, this gets it under the 65K mark.

Each language version/extension and target now has a "profile" containing
all of the available builtin function prototypes. These are written in
GLSL, and come directly out of the GLSL spec (except for expanding genType).
A new builtins/ir/ folder contains the hand-written IR for each builtin,
regardless of what version includes it. Only those definitions that have
prototypes in the profile will be included.
The autogenerated IR for texture builtins is no longer written to disk,
so there's no longer any confusion as to what's hand-written or
generated.
All scripts are now in python instead of perl.
