util/dump: Use static assertion to detect string table size mismatches.

Could probably be extended to other enums.

glsl: Remove VS output varyings which are optimized out of the FS

Previously when an input varying was optimized out of the
FS we would still retain it as an output of the VS.

We now build a hash of live FS input varyings rather
than looking in the FS symbol table. (The FS symbol table
will still contain the optimized out varyings.)

glapi: add ARB_texture_multisample

Adds new enums, dispatch machinery, and stubs for the 4 new entrypoints.

V2: - Drop placeholder
    - Align enum values
    - Remove explicit exec=mesa; it *is* the dispatch flavor we want,
      but it's also the default. I misunderstood how this worked before;
      after actually reading the generator it makes good sense.

V3: - Squash in stubs for new entrypoints, and dispatch_sanity tweaks,
      so we don't get build breakage between those patches.

V4: - Fix various remaining whitespace issues

mesa: add texobj support for ARB_texture_multisample

Adds the new texture targets, and per-image state for GL_TEXTURE_SAMPLES
and GL_TEXTURE_FIXED_SAMPLE_LOCATIONS.

V2: - Allow multisample texture targets in glInvalidateTexSubImage too.
      This was already partly there, but I missed it the first time around
      since the interaction is defined in a newer extension. Fixed weird
      indentation.
    - Allow multisample array textures in glFramebufferTextureLayer.
      This was overlooked as the tests originally only used 2d
      multisample textures.

V3: - Set min/mag filters sensibly for multisample textures. This
      can't actually be changed by the user, so it's more sensible to
      initialize it correctly than to hack around it being bogus later.

V4: - Tidy up initial min/mag filter setup. Setup in
      _mesa_initialize_texture_object was bogus, but benign since
      finish_texture_init() clobbered everything with correct values. For V4,
      just do the setup in finish_texture_init().

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
