    panfrost/midgard: Refactor opcode tables
    
    We create an all-encompassing opcode table for handling name and
    properties, removing a number of ad hoc opcode tables which became
    brittle and quickly out of date. While we're at it, we fix some
    incorrect opcodes relating to ball/bany, and move a small function out
    to midgard_compile.c. Together these changes should allow compilation
    without warnings, along with helping the codebase health considerably.

    panfrost/midgard: Implement copy propagation
    
    Most copy prop should occur at the NIR level, but we generate a fair
    number of moves implicitly ourselves, etc... long story short, it's a
    net win to also do simple copy prop + DCE on the MIR. As a bonus, this
    fixes the weird imov precision bug once and for good, I think.

    panfrost/midgard: Document sign-extension/zero-extension bits (vector)
    
    For floating point ops, these bits determine the "negate?" and "abs?"
    modifiers. For integer ops, it turns out they control how sign/zero
    extension work, useful for mixing types.

    panfrost/midgard: Update integer op list
    
    In the future, we might want to switch to a table-based approach, but
    for now, at least have it current.

    panfrost/midgard: Fix off-by-one in successor analysis
    
    This reduces register pressure substantially since we get smaller
    liveness ranges.

    panfrost/midgard: Dead code eliminate MIR
    
    We reshuffle the existing "dead move elimination" pass into a generic
    dead code elimination layer, fixing bugs incurred with looping in the
    process.

    panfrost: Use actual imov instruction
    
    The bug this worked around is no longer applicable, it seems -- remove
    the hack that breaks more than it fixes.

    panfrost: Disable indirect outputs for now
    
    The hardware needs this lowered anyway; for now, might as well use
    mesa's default lowering for pure conformance reasons.

    panfrost/midgard: imul can only run on *mul
    
    This restriction makes sense logically. Not sure why it wasn't obeyed
    before. In conjunction with previous commit's disclaimer, fixes
    dEQP-GLES2.functional.shaders.loop.for_dynamic_iterations.*

    panfrost/midgard: Don't try to inline constants on branches
    
    Along with a corresponding fix to the move elimination pass (not
    included here yet -- I just have it disabled for now), this will fix
    dEQP-GLES2.functional.shaders.loops.for_uniform_iterations.*

    panfrost: Respect backwards branches in RA
    
    Fixes a bunch of issues with looping. Honestly, I'm not sure why loops
    worked at all before.

    panfrost/midgard: Implement indirect loads of varyings/UBOs
    
    This adds preliminary support for indirect loads of varying arrays and
    uniform arrays, bringing a few new tests in shader.indexing.* to
    passing, although there remains a number of cases still missing.

    panfrost/midgard: Pipe through varying arrays
    
    Varying arrays sometimes are lowered to a series of directly accessed
    varyings (which we handled okay), but when indirectly accessed, they
    appear as a single array; we need to handle this as well.

    panfrost/mdg/disasm: Print raw varying_parameters
    
    The semantics of this field are not well understood; it is better to
    print it unconditionally along with the other unknown state, rather than
    silently eat the value. Without this change, some critical state was
    being lost in some shaders (notably, the offset for load/store
    scratchpad intructions found in shaders that spill registers.)
