Note that we can't actually remove the packed structs themselves yet,
because tu still uses them in some hand-coded blit shaders.

Also, uncomment the `stc` test vectors (since the new decoder decodes
these properly) and comment out an instruction which looks suspiciously
like -6.0 in hex.
This also switches the parser back to `atomic.b.op` from `atomic.op.b`
which was a short-term workaround to make it easier for the legacy
disassembler.
Also switch the binary encoding for ldib to clear b0, because the new
disassembler warns about unexpected dontcare bits (which cases the
disasm to not match).

Drops decoding an ~850KB collection of instructions from ~4min to ~1sec.
Granted for normal sized shaders, this probably doesn't matter.. but it
at reduces my cycle time for fixing things to match existing disasm
syntax using this massive collection of unique instructions.

Once we switch over to the xml based ir3 ISA definition, the opcodes
will be decoupled from instruction encoding. Which will let us better
handle cases where a single "opcode" (from instruction encoding stand-
point) means different things on different generations. And also cases
like the different variations of `b`ranch instructions, which share a
single hw "opcode" plus a separate "brtype" field. When we start using
these in ir3, we'd like to treat them as separate instructions and not
have to care about the details of how they are encoded.
For now, these are only used internally within the new xml generated
instruction encoding, but once the existing "packed struct" encoding/
decoding is replace, we'll update ir3 to start using the new opcode
enums directly (except for the `mov` variants).

We'll want to re-use this when cutting over to the new XML based
instruction encoding. So untangle it from instruction packing.
Also, move handling of the appended constant data out of the
assembler, since this isn't much related to instruction encoding.

This makes for a more self-describing iteration behavior, and it gets rid
of the need for the duplicated "final check" at the bottom.

All code paths that set "found" to true either break or return before the
loop header is reached again, so the checks are unnecessary.

This mainly clarifies the semantics of register bounds (inclusive vs
exclusive), and further groups related varaibles together to clarify
sliding-window-style loops.

Delaying the call to adjust_max_used_regs until after get_regs_for_copies
returns puts the RA context into a state where registers past max_used_gpr
may be blocked. This isn't an issue on its own, but it adds a surprising
corner case to get_reg_simple that is easily avoided now.
