Phase 5 (Runtime) Test Execution for Mojo Compiler
===================================================
This comprehensive test runner executes Phase 5 (Runtime) tests for the Mojo compiler
using the snake.mojo program. It verifies:
1. FFI Binding & Linking
- SDL3 library FFI symbols resolved
- Function pointers correctly linked
- Symbol table populated
2. Memory Management
- Heap initialization (1MB default)
- Allocation tracking
- Peak memory measurement
- Memory utilization
3. Full Execution
- Phases 1-4 compilation pipeline
- Runtime linking and initialization
- Program execution with timeout
- Exit code verification
Reports:
- FFI symbols linked count
- Memory allocation details
- Execution timing and status
- Exit codes and results
