We now express arrays in terms of indirect addressing. For example:
dst = a[i];
becomes:
MOV dst, TEMP[1 + TEMP[2].y];
At instruction-emit time indirect addressing is converted into ARL/
ADDR-relative form:
ARL ADDR.x, TEMP[2].y;
MOV dst, TEMP[1 + ADDR.x];
This fixes a number of array-related issues. Arrays of arrays and complex
array/struct nesting works now.
There may be some regressions, but more work is coming.

The Swizzle and Size fields carry all the info we need now.

This is a step toward better array handling code. In particular, when more
than one operand of an instruction uses indirect addressing, we'll need some
temporary instructions and registers. By converting IR storage to instruction
operands all in one place (emit_instruction()) we can be smarter about this.
Also, somewhat better handling of dst register swizzle/writemask handling.
This results in tighter writemasks on some instructions which is good for
SOA execution.
And, cleaner instruction commenting with inst_comment().
Next: remove some more dead code and additional clean-ups...

This lets one specify initial values for uniforms in the code, avoiding
the need to call glUniform() in some cases.

If an application never calls glUniform() to set sampler variable values
they'll remain 0 (the default value/unit).
Now call _mesa_update_shader_textures_used() at link time in case glUniform()
is never called. program->TextureUsed[] will then be correct for state
validation.

Expressions like array[i] + array[j] didn't work properly before.

The swizzle mask for such variables wasn't set up properly.

This fixes a function inlining bug involving vars declared inside loop bodies.

Commit 1680ef869625dc1fe9cf481b180382a34e0738e7 changed the texenv program
to get color from a state register instead of a constant-valued vertex
attribute. This broke program concatenation (so glDraw/CopyPixels broke).
Now check if the second program get's color from a constant register and
handle that case appropriately.

Calls to glBindAttribLocation() should not take effect until the next time
that glLinkProgram() is called.
gl_shader_program::Attributes now just contains user-defined bindings.
gl_shader_program::VertexProgram->Attributes contains the actual/final bindings.
