xenia-cpu: VMX128, FPSCR, decoder split, scheduler, decode/block caches
Split the monolithic interpreter into cohesive modules: dedicated decoder (decoder.rs) producing 8-byte DecodedInstr; opcode tables (opcode.rs); explicit traps (trap.rs); FPSCR helpers (fpscr.rs); overflow/carry helpers (overflow.rs); a 4 KiB-page-versioned decode cache and basic-block cache (block_cache.rs); and a full VMX/VMX128 implementation (vmx.rs) covering AltiVec + Xenon's 128-bit extensions. Add the parallel-execution substrate behind --parallel: a 7-party phaser (phaser.rs) for round-based barrier sync, ReservationTable (reservation.rs) for guest LL/SC, and the per-HW-thread scheduler core (scheduler.rs) that owns ThreadRefs, runqueues, and pending IRQs. Disassembler is now the single source of truth: disasm.rs gains the full base + extended + VMX128 mnemonic set, with golden JSON fixtures and a disasm_goldens test suite. Add a criterion-style interpreter bench. context.rs grows the per-thread state the new modules need (reservation slot, FPSCR, vector regs).

//! Assert-based goldens for the PPC disassembler.
|
||||
//!
|
||||
//! Each test owns an inline list of `(raw, addr, label)` cases. On a
|
||||
//! normal run, the test reads the corresponding fixture JSON and asserts
|
||||
//! that `format(decode(raw, addr))` reproduces every field exactly. On
|
||||
//! first creation (fixture file missing) or with `REGEN_GOLDENS=1` set,
|
||||
//! the test (re)writes the fixture from `format()` output.
|
||||
//!
|
||||
//! Workflow:
|
||||
//! ```sh
|
||||
//! cargo test -p xenia-cpu --test disasm_goldens # assert
|
||||
//! REGEN_GOLDENS=1 cargo test -p xenia-cpu --test disasm_goldens # regen
|
||||
//! ```
|
||||
//!
|
||||
//! The hand-encoded test cases below cover the silent-bug regression
|
||||
//! cases that lived in the old println-based `disasm_audit.rs` harness
|
||||
//! (now deleted).
