r300/compiler: Fix scheduler bug causing texture corruption

We weren't setting TEX_SEM_WAIT on instructions that read the value of a
TEX instruction and also wrote the same register as the TEX instruction.

This is the sequence we were miscompiling:

1: TEX temp[0], input[2].xy__, 2D[0]
...
16: src0.xyz = temp[22], src1.xyz = temp[0], src2.xyz = temp[19]
      MAD temp[0].xyz, src0.xxx, src1.xyz, src2.xxx
