    pan/bi: Add helpers for manipulating the ISA
    
    These will be used to generate various files for the IR.

    pan/bi: Add explicit meson dependency on the ISA helpers
    
    This logic was slightly busted before.

    We use this for non-parsing code as well. Make the name clear.

    pan/bi: Add staging register counts to ISA.xml
    
    Message-passing instructions that read/write staging registers access
    either:
    
    * a fixed number of registers
    * vecsize registers (/2 for LD/ST_CVT if register_format is 16-bit)
    * a computed number for TEXC
    
    This adds the fixed counts into the XML for the first type and space to
    specify the latter types.

    pan/bi: Mark message types in ISA.xml
    
    Message-passing instructions have an associated message type, which the
    clause header needs to signal. Instead of open coding this, let's
    annotate the XML. Instructions not otherwise marked do not generate
    messages.
    
    Three exceptions apply:
    
    * UBO loads need to use the attribute message type.
    * Tile buffer access to Z/S needs ZS message type
    * LD_VAR_SPECIAL.fragz needs ZS message type

    pan/bi: Mark some instructions as unused
    
    Certain transcendental instructions are not even possible to generate
    since these bits are lowered away before the Bifrost backend is touched,
    as far as I know.
    
    Job management instructions (most interestingly DOORBELL) do not
    correspond to OpenGL/OpenCL/Vulkan.
    
    Segment arithmetic seems mostly useless for real code, any actual use
    case I can think of is already covered by indirect loads/stores which
    does the segment arithmetic implicitly. I've never seen this in blob
    code, probably just a future proofing thing.
    
    Dropping these instructions corresponds to a 3% reduction in generated
    lines of code for the printer, builder, and packer for the new IR. Not a
    terrible yield for functionality we'll likely never need.

    pan/bi: Add pseudo-instruction mechanism
    
    Useful for instructions that need to be modeled in the IR (with support
    in the builder and printer) but will always be lowered away before
    packing since they don't correspond to anything real.

    pan/bi: Add unused instruction mechanism
    
    Certain instructions are highly unlikely to ever be used in the Bifrost
    compiler, due to differences in the Mesa stack versus the Arm compiler,
    as well as hardware features added speculatively and that never became
    API visible. It doesn't make sense to include these instructions in the
    IR, so let's disable them, while retaining complete disassembly.

    pan/bi: Drop on-board packing tests
    
    These tests were designed before having access to canonical information
    about the hardware and thus had two purposes:
    
    * Validating that our understanding of an instruction (as defined by IR
      semantics) matches hardware behaviour -- obsoleted by new information.
    
    * Validating that the IR packing code is correct -- obsoleted by
      rewriting the IR and rewriting the packing.
    
    I dislike removing tests as much as the next person, but the value of
    these will be nil by the end of the series, and will prove burdensome.
    Proper unit tests will be useful, however.
