This models instructions closer to the hardware. We'll deduplicate by
the end of the series, but for now this will allow us to add routines
operating on bi_instr without regressing existing users of
bi_instruction.

Alyssa Rosenzweig b85f317017 pan/bi: Add a helper to convert to old-style nodes 
RA, DCE, and liveness assume that SSA and non-SSA normal indices are
indexed from 1 in a shared address space, with a maximum given by
bi_max_temp. As a stop gap, let's translate bi_index to old style
node numbers so those passes can be updated cleanly.

Alyssa Rosenzweig 99152b6045 pan/bi: Add bi_index data structure 
Rather than open-coding indices with manual bit packing flying around,
let's add a data structure corresponding to a reference to some data.
(Think nir_src, ibc_ref, etc). In particular this allows us to pack in
more metadata, like an offset, for properly supporting limited vectors
(for I/O) without bloating the IR with swizzle fields.

Alyssa Rosenzweig 27f91eb66b 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
