First encoder-extension family. Adds Operand_Type VEC_SHIFT and Operand_Encoding NEON_SHL_IMM/NEON_SHR_IMM: the element-size marker bit sits in the entry's bits, the encoder packs the amount into the low immh:immb bits (left = shift; right = esize - shift, esize from the vector operand via vec_esize/form.ops[0]), and the decoder recovers esize from immh to compute the amount. Adds 13 mnemonics (91 forms) via specgen: left SHL/SLI/SQSHLU/SQSHL, right SSHR/USHR/SRSHR/URSHR/SSRA/USRA/SRSRA/URSRA/SRI. specgen derives bits/mask empirically by varying registers AND the shift (canon = operand bits zero; other extreme sets all shift bits), so per-arrangement immh discrimination + the growing shift-field width fall out automatically. Verified end-to-end: encode matches llvm-mc byte-for-byte AND decode recovers mnemonic + amount (sshr/shl/sli/ushr/srsra across B/H/S/D); arm64 check + 461 tests pass. First of the encoder-extension phase ([[rexcode-encode-coverage]]); CCMP_IMM imm5@20:16 pattern generalizes here.

The Odin Programming Language
Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.
