    nv50: introduce emit_cvt and use it
    
    This makes some code cleaner, and we can now easily
    do CEIL and TRUNC.

    nv50: fix TXP
    
    For TXP we need to divide texture coords by their w component, or
    use the coords' 1/w in the perspective interpolation instruction.
    
    This also tries to support 1D, 3D and CUBE textures, and lets the
    instruction only load the components that are used.

    nv50: use multiple constant buffers
    
    Use different buffers for immds, FP params, and VP params.
    One has to map constant buffer indices in shader code to buffers
    defined via CB_DEF. In principle, we could use more buffers so
    we'd have to change the shader code less frequently.

    nv50: don't look for unfreed temps in free_nv50_pc
    
    Since we stopped using alloc_temp to get hw indices for FP attrs
    there shouldn't be any non-deallocated temps left.

    nv50: release hw TEMPs early
    
    Since we know when we don't use a TEMP or FP ATTR register anymore,
    we can release their hw resources early.

    nv50: allow immediates for MOV, ADD and MUL
    
    Immediates are inlined now where possible, so we need to set
    pc->allow32 to FALSE in LIT where we have the conditional MOV,
    since immediates swallow the predicate bits.

    nv50: enable half insns for MOV and MUL

    nv50: make sure half-long insns are paired
    
    I chose to just convert unpaired 32 bit length instructions
    after parsing all instructions, although it might be possible
    to determine beforehand whether there would be any lone ones,
    and then even do some swapping to bring them together ...

    nv50: don't overwrite sources before they're used
    
    This would have happened in p.e. ADD TEMP[0], TEMP[0].xyxy, TEMP[1]
    or RCP/RSQ TEMP[i], TEMP[i].

    nv50: put FP outputs where they belong
    
    Depth output in fragment programs should end up in the first
    register after the color outputs.

    nv50: modified FP attribute loading
    
    VP outputs that should be loadable in the FP are mapped to
    interpolant indices by HPOS, COL0 etc.; of course HPOS is
    always written, so the highest byte of 1988 is a bitmask that
    selects which components of HPOS are used for interpolants,
    i.e. the FP inputs in COL0 start at index POPCNT(1988[24:28]).

    nv50: inspect decl semantic and interpolation mode
    
    Record interpolation mode for attributes while parsing declarations,
    and also remember the indices of FP color inputs and FP depth output,
    which has to end up in the highest output register.

    nv50: record last access to temp and attr regs
    
    We now inspect the TGSI instructions in tx_prep to determine where
    temps and FP attrs are last accessed.
    This will enable us to reclaim some temporaries early and we also
    use it to omit pre-loading FP attributes that aren't used.

    nv50: save some space in immediate buffer
    
    We could do even better (like just allocating 1 value in alloc_immd),
    but that's fine for now I guess.

    nv50: set dst.z,w to 0,1 in SCS and XPD
    
    According to tgsi-instruction-set.txt, if they are written, z and w
    should be set to 0 and 1 respectively in SCS, and w to 1.0 in XPD.

    nouveau: explicitly request mappable buffers for the moment
