    freedreno/ir3: add NIR compiler
    
    The NIR compiler frontend is an alternative to the TGSI f/e, producing
    the same ir3 IR and using the same backend passes for scheduling, etc.
    
    It is not enabled by default yet, as there are still some regressions.
    To enable, use 'FD_MESA_DEBUG=nir'.  It is enough to use with, for
    example, xonotic or supertuxkart.
    
    With the NIR f/e, scalarizing and a number of other lowering steps
    happen in NIR, so we don't have to do them in ir3.  Which simplifies the
    f/e and allows the lowered instructions to pass through other
    optimization stages.

    freedreno/a3xx: pass sprite coord mode through to program emit
    
    Use the correct sprite replacement depending on the flip of the coord
    mode, using either T or 1-T depending on whether we have an upper-left or
    lower-left coordinate origin. This fixes all the point sprite piglits.

    freedreno: fix resource flushing confusion
    
    A resource flush is an upload of a hypothetically-staging texture to the
    GPU. For a UMA system, this will largely be a no-op or
    cache-maintenance. Move the render flush logic into transfer_map where
    it belongs, and clear out the transfer_flush function.

    freedreno/ir3/cmdline: add @const headers for immediates
    
    Since NIR f/e currently encodes immediates in instructions (rather than
    passing via const), we need to ensure that when const's are used the get
    initialized to the proper values.  Otherwise comparing NIR to TGSI
    compiler, it will use proper immediate values in one case, and randomly
    initialize values in the other.  Which confuses ir3test.

    freedreno/ir3: handle const/immed/abs/neg in cp
    
    Be smarter about propagating copies from const or immed, or with abs/neg
    modifiers.  Also, realize that absneg.s and absneg.f are really "fancy"
    mov instructions.
    
    This opens up the possibility to remove more copies.  It helps the TGSI
    frontend a bit, but will be really needed for the NIR f/e which builds
    everything up in SSA form (ie. will *always* insert a mov from const or
    immediate).

    freedreno/ir3: split float/int abs/neg
    
    Even though in the end, they map to the same bits, the backend will need
    to be able to differentiate float abs/neg vs integer abs/neg.  Rather
    than making the backend figure it out based on instruction opcode (which
    when combined with mov/absneg instructions, can be awkward), just split
    out different flags for each so the frontend can signal it's intentions
    more clearly.  Also, since (neg) for bitwise op's is actually a bitwise-
    not, split it out into bnot flag.

    xa: support for drivers which use NIR
    
    We need to pull in libnir.la and it's dependency libglsl_util.la.  Also,
    _mesa_error_no_memory() must be defined.
    
    Fortunately with libnir.la (vs pulling in all of libglsl.la) we don't
    also need libstdc++.

    build: add libnir.la
    
    If we want to use NIR from state trackers that don't already pull in the
    whole of glsl (ie. anything other than mesa state tracker), we need a
    separate more minimal libnir.  Possibly NIR should be better split out
    from glsl, but for now, generate a second smaller libnir.la for those
    who just want NIR but not all of glsl.

    nir: add lowering for idiv/udiv/umod
    
    Based on the algo from NV50LegalizeSSA::handleDIV() and handleMOD().
    See also trans_idiv() in freedreno/ir3/ir3_compiler.c (which was an
    adaptation of the nv50 code from Ilia Mirkin).
    
    A python/numpy script which implements the same algorithm (and is
    possibly useful for debugging or analysis) can be found here:
    
      http://people.freedesktop.org/~robclark/div-lowering.py
    
    I've tested this on i965 hacked up to insert the idiv lowering pass,
    and on freedreno with NIR frontend.

    In freedreno these get implemented as the matching f* instruction plus a
    u2f to convert the result to float 1.0/0.0.  But less lines of code to
    just let nir_opt_algebraic handle this for us, plus opens up some small
    window for other opt passes to improve (ie. if some shader ended up with
    both a flt and slt with same src args, for example).
