Adds 25 Advanced-SIMD three-same integer mnemonics (153 forms across arrangements) to ENCODING_TABLE: SHADD/UHADD/SHSUB/UHSUB/SRHADD/URHADD, SQADD/UQADD/SQSUB/UQSUB, SMAX/UMAX/SMIN/UMIN, SABD/UABD/SABA/UABA, MLA/MLS, CMGE/CMHS/CMTST, SQDMULH/SQRDMULH. Introduces tablegen/specgen.lua: compact specs (mnemonic + llvm name + arrangements) -> ENCODING_TABLE blocks, with bits taken from llvm-mc (the oracle) and mask derived empirically (vary registers 0..31). Invalid arrangements are auto-detected via llvm-mc and skipped. Output fills the SPECGEN:BEGIN..END region of encoding_table.odin in place; the hand-written core is untouched. Verified: decode round-trips for SHADD/SQADD/CMGE/SQRDMULH; arm64 check + 461 tests pass; builders auto-generate (780 -> 805). Caveat: NEON builders currently collapse arrangements (one Register param per V operand) so inst_<mnem> exposes only the first arrangement -- an arrangement-aware builder-gen pass follows.
