XSAVE, XSAVEOPT, XSAVEC and XSAVES with their restore twins, plain and
64, each pinned byte for byte against go tool asm through every corpus
line the toolchain's own amd64enc.s carries for the family (24 lines).
The toolchain emits XSAVEOPT without the manual's 0x66 prefix; the bytes
are the oracle, so the family carries none.

The no-operand flag and system controls, the sign-extension pair, the
string primitives, the multi-byte no-ops, the cache controls, MOVBE, the
compare-exchange doubles, the random source and FS/GS base pairs, the
descriptor-table accesses, the 0F 00/01 register controls and the
LAR/LSL selector reads and far-segment loads, each pinned byte for byte
against go tool asm through every corpus line the toolchain's own
amd64enc.s carries for the families (279 lines).

The x87 stack controls, the D8/DC arithmetic pair, the conditional moves,
the register compares, FADDDP, the memory loads and the FXSAVE pair, each
pinned byte for byte against go tool asm through every corpus line the
toolchain's own amd64enc.s carries for the family (78 lines).
