    freedreno/ir3: pass sz to split_dest()
    
    For query_levels, we generate a getinfo with writemask of (z), which RA
    will consider as size==3.  But we were still generating four fanouts.
    Which meant that RA would see it as two different register classes,
    depending on the path to definer.  Ie. on the getinfo instruction itself
    it would see size==3, but when chasing back through the fanouts it would
    see size==4.
    
    Easiest way to solve that is to just generate the chain of neighboring
    fanouts to have the correct size in the first place.
    
    Note: we may eventually want split_dest() to take start/end or wrmask
    instead, since really we only need size==1.  But RA is not clever enough
    for that, query_levels is not that common, and the other two registers
    that get allocated are never used so those register slots can be
    immediately re-used.  So bunch of work for probably no real gain.

    freedreno/ir3: only unminify txf coords on a3xx
    
    Seems like a4xx gets this right.

    freedreno: remove int sampler shader variants
    
    We get this information from NIR (which gets it from sview decl in tgsi
    when translating from tgsi), so no need to maintain shader variants for
    this.

    freedreno/ir3: block reshuffling and loops!
    
    This shuffles things around to allow the shader to have multiple basic
    blocks.  We drop the entire CFG structure from nir and just preserve the
    blocks.  At scheduling we know whether to schedule conditional branches
    or unconditional jumps at the end of the block based on the # of block
    successors.  (Dropping jumps to the following instruction, etc.)
    
    One slight complication is that variables (load_var/store_var, ie.
    arrays) are not in SSA form, so we have to figure out where to put the
    phi's ourself.  For this, we use the predecessor set information from
    nir_block.  (We could perhaps use NIR's dominance frontier information
    to help with this?)

    freedreno/ir3: a4xx encodes larger immed offset
    
    Without this, negative branch/jump offsets look like very large positive
    offsets.

    freedreno/ir3: move inputs/outputs to shader
    
    These belong in the shader, rather than the block.  Mostly a lot of
    churn and nothing too interesting.  But splitting this out from the
    rest of ir3_block reshuffling to cut down the noise in the later
    patch.

    freedreno/ir3: introduce ir3_compiler object
    
    Right now, just provides a cleaner way to get at the gpu-id, given the
    separation between compiler and context.  But we will need this also to
    hold the reg-set for new register allocation.

    freedreno/ir3: use standard list implementation
    
    Use standard list_head double-linked list and related iterators,
    helpers, etc, rather than weird combo of instruction array and next
    pointers depending on stage.  Now block has an instrs_list.  In
    certain stages where we want to remove and re-add to the blocks list
    we just use list_replace() to copy the list to a new list_head.

    glsl_to_tgsi: add SVIEW decl support
    
    Freedreno needs sampler type information to deal with int/uint textures.
    To accomplish this, start creating sampler-view declarations, as
    suggested here:
    
     http://lists.freedesktop.org/archives/mesa-dev/2014-November/071583.html
    
    create a sampler-view with index matching the sampler, to encode the
    texture type (ie. SINT/UINT/FLOAT).  Ie:
    
       DCL SVIEW[n], 2D, UINT
       DCL SAMP[n]
       TEX OUT[1], IN[1], SAMP[n]
    
    For tgsi texture instructions which do not take an explicit SVIEW
    argument, the SVIEW index is implied by the SAMP index.
