Yukihiro "Matz" Matsumoto a07d9fb62c vm.c: optimize OP_GETIDX with branch hints and reduced checks ...

- Add mrb_likely/mrb_unlikely macros to common.h for branch prediction
- Optimize OP_GETIDX array fast path:
  - Cache RArray pointer to avoid repeated RARRAY() calls
  - Single ARY_EMBED_P check instead of two (via RARRAY_LEN + RARRAY_PTR)
  - Use unsigned comparison for bounds check
  - Add branch prediction hints for common cases
- Convert switch statement to if-else chain for better branch prediction

Benchmark shows ~3% improvement for array read operations.
