Silences MSVC.

This fixes cases such as:
vec4 v4;
vec2 v2;
v4.xz.yx = v2;
The last line now correctly compiles into MOV TEMP[1].xz, TEMP[0].yyxw;
Helps to fix the Humus Domino demo. See bug 19189.

Now only the samplers that are actually used by texture() functions are
saved in the uniform variable list. Before, we could run out of samplers
if too many were declared while only some of them were actually used.

This allows code such as "vec4 a = gl_LightSource[i].ambient;" to work.
When a built-in uniform array is indexed with a variable index we need to
"unroll" the whole array into the parameter list (aka constant buffer) because
we don't know which elements may be accessed at compile-time. In the case of
the gl_LightSource array of size [8], we emit 64 state references into the
parameter array (8 elements times 8 vec4s per gl_LightSourceParameters
struct).
Previously, we only allowed constant-indexed references to uniform arrays
(such as gl_LightSource[2].position) which resulted in a single state reference
being added to the parameter array, not 64. We still optimize this case.
Users should be aware that using "gl_LightSource[i].ambient" in their shaders
is a bit expensive since state validation will involve updating all 64
light source entries in the parameter list.

array.length() wasn't working.
Swizzle mask for accessing elements of float arrays was incorrect.

This allows uniform declarations with scalar/array initializers.
The code is rough though, and will be cleaned up.

For example, a declaration like
const float[3] xxx = float[3](1.1, 2.2, 3.3);
will place the array in the constant buffer whereas a regular, non-const array
would be placed in the temporary register file.
Next up: do the same thing for uniform arrays.
