Register Allocation Benchmarks for ScratchV.

This package contains three benchmark suites for the linear scan
register allocator (``LinearScanAllocator``):

1. **bench1_simple** — Simple arithmetic (3-5 vregs, no spills)
2. **bench2_dense** — Dense computation (20+ vregs, triggers spilling)
3. **bench3_cnn** — CNN model integration (operations from ``models/graph/cnn.onnx``)

Each suite measures allocation time, spill count, peak register pressure,
and validates output correctness.

Usage::

python -m benchmarks.test_regalloc.run_all
