Before, we were always using the address register and indirect addressing
to index into a UBO constant buffer. With this change we only do that
when necessary.
Using the piglit bin/arb_uniform_buffer_object-rendering test as an
example:
Shader code:
uniform ub_rot {float rotation; };
...
m[1][1] = cos(rotation);
Before:
IMM[1] INT32 {0, 1, 0, 0}
1: UARL ADDR[0].x, IMM[1].xxxx
2: MOV TEMP[0].x, CONST[3][ADDR[0].x].xxxx
3: COS TEMP[1].x, TEMP[0].xxxx
After:
0: COS TEMP[0].x, CONST[3][0].xxxx
