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)

Note that while 'packed' is a reserved word in GLSL ES, row_major is not.
This means that we have to use the string-based matching for that.

This patch turns on the following features for GLSL ES 3.00:
- Array constructors, whole array assignment, and array comparisons.
- Second and third operands of ?: may be arrays.
- Use of "in" and "out" qualifiers on globals.
- Bitwise and modulus operators.
- Integral vertex shader inputs.
- Range-checking of literal integers.
- array.length method.
- Function calls may be constant expressions.
- Integral varyings must be qualified with "flat".
- Interpolation and centroid qualifiers may not be applied to vertex
shader inputs.

GLSL ES 3.00 adds the following keywords over GLSL 1.00: uint,
uvec[2-4], matNxM, centroid, flat, smooth, various samplers, layout,
switch, default, and case.
Additionally, it reserves a large number of keywords, some of which
were already reserved in versions of desktop GL that Mesa supports,
some of which are new to Mesa.
A few of the reserved keywords in GLSL ES 3.00 are keywords that are
supported in all other versions of GLSL: attribute, varying,
sampler1D, sampler1DShador, sampler2DRect, and sampler2DRectShadow.
This patch updates the lexer to handle all of the new keywords
correctly when the language being parsed is GLSL 3.00 ES.

This patch expands the lexer KEYWORD macro to take two additional
arguments: the GLSL ES versions in which the given keyword was first
reserved, and supported, respectively. This will allow us to
trivially add support for GLSL 3.00 ES keywords, even though the set
of GLSL 3.00 ES keywords is neither a subset or a superset of the
keywords corresponding to any desktop GLSL version.
The new KEYWORD macro makes use of the
_mesa_glsl_parse_state::is_version() function, so it accepts 0 as
meaning "unsupported" (rather than 999, which we used previously).
Note that a few keywords ("packed" and "row_major") are supported
*either* when GLSL 1.40 is in use or when ARB_uniform_buffer_obj
support is enabled. Previously, we handled these by cleverly taking
advantage of the fact that the KEYWORD macro didn't parenthesize its
arguments in the usual way. Now they are handled more
straightforwardly, with a new macro, KEYWORD_WITH_ALT.

This adds all the new builtins + the new sampler types,
and hooks them up if the extension is supported.
v2: fix missing signatures for grad/lod
fix missing textureSize clarifications
fix compare vs starts with usage

This doesn't do anything with the uniform block declarations yet, so
usage of those uniforms finds them to be undeclared.

The non-integer versions were already reserved in 1.30, but apparently
these were forgotten.

From page 22 (28 of PDF) of GLSL 1.30 spec:
It is an error to provide a literal integer whose magnitude is too
large to store in a variable of matching signed or unsigned type.
Unsigned integers have exactly 32 bits of precision. Signed integers
use 32 bits, including a sign bit, in two's complement form.
Fixes piglit int-literal-too-large-0[123].frag.
v2: Take care with INT_MIN, use stroull, and make it a function.

SCons has built-in support for .ll and .yy, but not .lpp and .ypp. Since
there's no real benefit to using the old names, change them.
