petrbalvin a7f9d5eb67 feat(disasm): render the loong64 families x/arch names Unknown
x/arch's Plan 9 renderer decodes thirty-odd scalar loong64 operations
perfectly but prints them as "Unknown OP args", and names the
sign-extension pair EXT.W.B/EXT.W.H "?".  The supplementary naming
pass re-renders them with the toolchain's own spellings: the families
whose operand order x/arch already prints the Plan 9 way trade only
the mnemonic, and the pointer loads and stores, the acquire loads,
the release stores, PRELD and ALSL are rebuilt from the decoded
arguments with the toolchain's operand order and its raw displacement
reading.  ADDU16I.D, a macro helper the assembler never takes as
input, keeps the decoder's Unknown render.

The loong64 parity fixture grows from 73 to 385 rows, pinning every
unique four-byte corpus word the decoder accepts, and the LL/SC
displacement divergence in the encoder is documented for asm.

petrbalvin 0f6e008c9a feat(disasm): name the arm64 words arm64asm refuses
arm64asm rejects three exception-space words the toolchain's corpus
assembles: the hypervisor call HVC, the secure monitor call SMC and
the speculation barrier SB.  The supplementary naming table reads
the raw word in the error branch and renders the corpus spellings;
the corpus rows are pinned in the parity fixture and the boundary
test holds the unallocated neighbours on the placeholder.

petrbalvin 458d981f31 feat(disasm): name the CLDEMOTE encoding the decoder refuses
The hint NOP opcode 0F 1C /r with a memory operand is CLDEMOTE, a
memory-only instruction the toolchain's own table carries; the decoder
rejects the encoding instead of naming it.  The rejected-encoding side
of the supplementary table names it from the bytes, and the corpus row
0f1c03 pins the text in the unlisted fixture, round trip byte exact.

petrbalvin dd356b9e6a fix(disasm): name the amd64 families x/arch decodes to the zero opcode
x/arch reports the ADCX, ADOX, RDSEED, RDPID, TPAUSE, UMONITOR, UMWAIT
and ENDBR families with no error but the degenerate zero instruction,
which GoSyntax renders as Op(0) under its prefix decoration and with a
length of one.  A supplementary naming table keyed by the opcode
pattern restores the toolchain's own spellings and lengths; the parity
fixtures pin all 41 corpus rows (ENDBR32 alone, which the toolchain
cannot spell, pins as bytes and text in the focused naming test).
