Roll the encode/decode buffer-sizing helpers (added for x86 in 49787b7de) out
to every other ISA, and document them in the cross-arch naming contract.
Per arch (arm32, arm64, mips, riscv, ppc, ppc_vle, rsp, mos6502, mos65816):
- encode_max_code_size / encode_max_relocation_count now key off the
[]Instruction slice (were int counts); bodies unchanged (* MAX_INST_SIZE).
- encode_reserve(code, relocs, instructions): grows the caller's code []u8 by
length and reserves relocs by capacity; allocates no new buffers.
- decode_max_instruction_count / decode_estimate_instruction_count: exact
ceiling and typical estimate, keyed off the min/avg instruction size per
arch (fixed-4: arm64/mips/ppc/rsp; min-2: arm32/riscv/ppc_vle; min-1: mos).
- decode_reserve(instructions, inst_info, label_defs, data, exact=false).
docs/cross_arch_design.md: helpers added to the naming contract.
No behavior change to the existing size helpers (signature only). All 10 ISAs
check + test green (x86 2282, arm32 600, arm64 461, mips 281, riscv 154, ppc 31,
ppc_vle 281, rsp 70, mos6502 148, mos65816 53).

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.
