Merge origin/bill/rexcode: struct repack (#raw_union #packed), wasm arch

Browse Source 
Merge gingerBill's latest into bill/rexcode. His changes: minimize the
Instruction/Operand structs across ISAs with packed raw-unions (+ the
compiler support for #raw_union #packed), the new core:rexcode/wasm arch
and wasm/module, encode() now returns (byte_count, ok) instead of a Result
struct, decode_one made public, and assorted formatting/inlining.

Conflict: arm64/tests/pipeline_smoke.odin CSEL test -- kept the generated
4-arg inst_csel(dst,src,src2,cond) (mnemonic_builders.odin is generated,
not from Bill's branch) and adopted Bill's (byte_count, success) encode
signature.

Required rebuilding ./odin from the merged source for the packed-union
syntax. Re-validated after the repack: regenerated all artifacts
(idempotent -- no spurious churn), all 10 arches gen/builders/check/test
green, and byte-compared the new arm32 BF + mips PS/MMI/DSP/R6 forms to
confirm no field truncation. arm64/arm32/mips still 100%.
