We will need that for blend shaders so they can be passed a return
address and jump back to the fragment shader when they're done.

This is needed for BLEND instructions used from a blend shader so we can
store the result of the shader-based blending back to the tile buffer.
We let the gallium driver build this blend descriptor for us in order
to keep the compiler cmdstream-agnostic.

If a block ends in an unconditional jump, we don't need to record a
fallthrough successor as well, since it's unreachable.
Likely harmless but makes the IR harder to parse with messy CF graphs.

This makes it explicit that this intrinsic is only for SSBOs. For the
v3dv driver, we'll be adding a get_ubo_size intrinsic and we want to be
able to distinguish between the two.
