petrbalvin 6af3fd60d5 feat(asm): encode the legacy amd64 SSE and MMX families 
The packed integer and float binaries, the imm8-controlled SSE4.1 forms,
the variable blends with their X0 mask, the high/low half moves, the
sign-mask extractions, the non-temporal stores, the MOVQ bank crossings
and their odd spellings, the MMX shifts and shuffle and the cache-line
mask stores, plus the scalar leaves LEAVE, INVPCID and the RTM controls.
Every encoding is pinned byte for byte against go tool asm through every
corpus line the toolchain's own amd64enc.s carries for the families
(1465 lines).  Two corpus-wide gaps fell out of the comparison: the
64-bit MOV immediate uses the zero-extending form across the unsigned
32-bit span, and the MMX-to-GPR MOVQ puts the bank register in reg.

petrbalvin 257feace6e feat(asm): encode the amd64 XSAVE family 
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.

petrbalvin f83bc8ddef feat(asm): encode the amd64 system, string and segment families 
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).

petrbalvin f0b08ccea0 feat(asm): encode the amd64 x87 family 
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).
