Updated GLSL uniform/sampler handling from gallium-0.1 branch
...
Previously, the shader linker combined the uniforms used by the vertex and
fragment shaders into a combined set of uniforms. This made the implementation
of glUniform*() simple, but was rather inefficient otherwise. Now each shader
gets its own set of uniforms (no more modelview matrix showing up in the
fragment shader uniforms, for example).
cherry-picked by hand from gallium-0.1 branch

Add the ability to generate programs that doesn't use condition codes.
...
ctx->Shader.EmitCondCodes determines if we use condition codes.
If not, IF statement uses first operand's X component as the condition.
Added OPCODE_BRK0, OPCODE_BRK1, OPCODE_CONT0, OPCODE_CONT1 to handle
the common cases of conditional break/continue.

Overhaul handling of writemasks/swizzling. This fixes two problem cases:
...
vec2 v; v.x = v.y = 1.0; // chained assignment
vec4 v; v.zx = vec2(a,b); // swizzled writemask
