    v3d: Use the new lower_to_scratch implementation for indirects on temps. · dc402be7
    Eric Anholt authored
    We can use the same register spilling infrastructure for our loads/stores
    of indirect access of temp variables, instead of doing an if ladder.
    
    Cuts 50% of instructions and max-temps from 2 KSP shaders in shader-db.
    Also causes several other KSP shaders with large bodies and large loop
    counts to not be force-unrolled.
    
    The change was originally motivated by NOLTIS slightly modifying register
    pressure in piglit temp mat4 array read/write tests, triggering register
    allocation failures.
