Which shader instruction uses this? Afair vertex shaders should only use TA,
but there's no proper infrastructure that manages that.
AFAICS, TB could get used in shader_hw_pow():
...
   shader_arb_get_src_param(ins, &ins->src[1], 1, src1);
...
where the '1' in the third argument means that
shader_arb_get_src_param() is allowed to use TB as temporary storage.
There may be other pieces of code with the same assumption, I didn't
look deeper.
