Drew T bd45f1f232 feat(decomp): main lane m13 — 34 banked 
One clean whole-EXE rebuild verified the batch (gate_main), and main re-checked
BYTE-IDENTICAL against config/check.us.sha before anything was credited.

/*
* GsTMDfastG3GL (0x80057928) -- PsyQ libgs, HANDWRITTEN assembly (splat marks it
* "Handwritten function"). It is raw GTE code: cop2 compute ops (rtpt/nclip/avsz3/nccs),
* direct lwc2/swc2 to numbered cop2 data registers, cfc2 $31, hand-filled branch delay
* slots and explicit cop2/load-latency nops, 8 arguments (4 in $a0-$a3, 4 on the stack),
* and an allocation that uses only $t0-$t7. gcc-2.7.2 -O2 cannot emit any of this from C.
*
* So it is reproduced the way the project's other handwritten GTE bodies are
* (cookbook: DEFINE_func_8013E2C4 et al.): the whole body is one __asm__ __volatile__
* block. gcc supplies only the label and the zero-frame leaf epilogue (`jr $ra` + nop),
* which is exactly the target's tail. The GTE compute ops are written as `cop2 <imm>`
* because binutils has no rtpt/nclip/avsz3/nccs mnemonics (the splat .s gets them from
* include/gte_macros.inc, which is not reachable from inline asm):
* rtpt = 0x4A280030 -> cop2 0x0280030
* nclip = 0x4B400006 -> cop2 0x1400006
* avsz3 = 0x4B58002D -> cop2 0x158002D
* nccs = 0x4B08041B -> cop2 0x108041B
* No relocations and no symbol references at all: the function touches only its
* arguments and the GTE.

* GsTMDfastG4GL @ 0x8005845C -- HANDWRITTEN PsyQ libgs TMD primitive walker
* (gouraud, 4-vertex, lit, non-textured "fast" path).
*
* Splat marks this "Handwritten function": it is raw GTE assembly, not
* compiler output --
* - long-lived state in $t0..$t9 (never gcc's allocation order),
* - extra arguments read from the CALLER's frame at 0x18..0x24($sp) after a
* manual `addiu $sp,$sp,-8`, i.e. a private calling convention,
* - cop2 data-register traffic (lwc2/swc2 $0..$27), rtpt/rtps/nclip/avsz4/
* nccs, `cfc2 $t4,$31` flag reads and the mandatory cop2-latency `nop`s.
* None of that is reachable from C, so the body is written as one full inline
* asm block (cookbook: the func_801285E4 / func_80128714 full-inline-asm
* handwritten-wrapper idiom, and the §"handwritten GTE sqr" note).
*
* maspsx interaction (this is the whole trick):
* - the leading `.set<TAB>noreorder` is written with a TAB so maspsx's own
* is_reorder tracker flips to False -- otherwise maspsx auto-fills EVERY
* branch delay slot with a nop, and this function has REAL instructions in
* its delay slots (`sw $v1,16($t1)`, `addiu $v0,$a3,32`, `addiu $t2,..`).
* - maspsx's load-delay pass (_handle_nop_before_next_instruction) is NOT
* gated on is_reorder: it still injects a nop when the next instruction
* re-reads a load's destination through a base register. That fires exactly
* once here, on `lw $v0,56($t1)` -> `lw $v0,0($v0)`, so that one latency nop
* is deliberately NOT written by hand (maspsx emits it).
* - every memory offset is DECIMAL: maspsx's store path calls int(operand)
* base-10 and would raise on "0x38".
*
* Shape of the routine:
* for (i = 0; i < n; i++) // n = arg at 0x18($sp), prim stride 0x24
* RTPT the three leading vertex indices, bail on GTE flag bit31,
* NCLIP + backface/otz reject, RTPS the 4th vertex, AVSZ4 -> OT bucket
* (ot_base + ((otz >> shift) << 2)), then four NCCS colour passes writing
* the packet, and link the packet into the OT.
