r600: Disable SB in the presence of indirection on temp arrays.

r600: Disable SB in the presence of indirection on temp arrays.

Prevents several regressions when NIR-to-TGSI is enabled where it was
allocating arrays on top of each other.

Fixes vec3 fails on RV770,
dEQP-GLES3.functional.shaders.metamorphic.bubblesort_flag.variant_1 and 2
in general, and fixes another piglit but breaks two others.  Still, this
seems to be a win.
