Mesa's extension table incorrectly lists this GL_OES_texture_npot as
ES2-only. It's also an ES1 extension. This patch adds ES1 to the
extensions API mask.
From the GL_OES_texture_npot spec:
OpenGL ES 1.0 or OpenGL ES 2.0 is required. This extension is
written against OpenGL ES 1.1.12 and OpenGL ES 2.0.25.

Now that all the places that used to generate array derefeneces of
vectors have been changed to generate either ir_binop_vector_extract or
ir_triop_vector_insert (or both), remove all support for dealing with
this deprecated construct.
As an added safeguard, modify ir_validate to reject ir_dereference_array
of a vector.

Like with type conversions on out parameters, some extra copies need to
occur to handle these cases. The fundamental problem is that
ir_binop_vector_extract is not an lvalue, but out and inout parameters
must be lvalues. A previous patch delt with a similar problem in the
LHS of ir_assignment.

Variable indexing into vectors using ir_dereference_array is being

Right now the lower_clip_distance_visitor lowers variable indexing into
gl_ClipDistance into variable indexing into both the array
gl_ClipDistanceMESA and the vectors of that array. For example,
gl_ClipDistance[i] = f;
becomes
gl_ClipDistanceMESA[i >> 2][i & 3] = f;
However, variable indexing into vectors using ir_dereference_array is
being removed. Instead, ir_expression with ir_triop_vector_insert will
be used. The above code will become
gl_ClipDistanceMESA[i >> 2] =
vector_insert(gl_ClipDistanceMESA[i >> 2], i & 3, f);
In order to do this, an ir_rvalue_visitor will need to be used. This
commit is really just a refactor to get ready for that.
v4: Split the least amount of refactor from the rest of the code
changes.

This will eventually replace do_vec_index_to_cond_assign. This lowering
pass is called in all the places where do_vec_index_to_cond_assign or
do_vec_index_to_swizzle is called.
v2: Use WRITEMASK_* instead of integer literals. Use a more concise
method of generating broadcast_index. Both suggested by Eric.
v3: Use a series of scalar compares instead of a single vector compare.
Suggested by Eric and Ken. It still uses 'if (cond) v.x = y;' instead
of conditional assignments because ir_builder doesn't do conditional
assignments, and I'd rather keep the code simple.

This pass flips (matrix * vector) operations to (vector *
matrixTranspose) for certain built-in matrices (currently
gl_ModelViewProjectionMatrix and gl_TextureMatrix).
This is equivalent, but results in dot products rather than multiplies
and adds. On some hardware, this is more efficient.
This pass is conditionalized on ctx->mvp_with_dp4, the flag drivers set
to indicate they prefer dot products.
Improves performance in Lightsmark by 1.01131% +/- 0.162069% (n = 10)
on a Haswell GT2 system. Passes Piglit on Ivybridge.
v2: Use struct gl_shader_compiler_options instead of plumbing through
another boolean flag for this purpose.

Doing matrix multiplies with DP4s is fewer instructions than MUL/ADD,
especially since we don't support MAD in the vertex shader.
Not observed to improve performance in any fixed function applications,
but is useful for the next patch.
I've left this unset for the fragment shader because the scalar backend
can't use DP4 and does have MAD support.

This flag essentially tells the compiler whether it prefers
dot products or multiply/adds for matrix operations. As such,
ShaderCompilerOptions seems like the right place for it.
This also lets us specify it on a per-stage basis. This patch makes all
existing users set the flag for the Vertex Shader stage only, as it's
currently only used for fixed-function vertex programs. That will
change soon, and I wanted to preserve the existing behavior.

do_common_optimization may need to make choices about whether to emit

Previously, we would sometimes not consider a write to a register to
extend the end of the interval, nor would we consider a read before a
write to extend the start. This made for a bunch of complicated logic
related to how to treat the results when dead code might be present.
Instead, just extend the interval and fix dead code elimination to know
how to remove it.
Interestingly, this actually results in a tiny bit more optimization:
total instructions in shared programs: 1391220 -> 1390799 (-0.03%)
instructions in affected programs: 14037 -> 13616 (-3.00%)
