Feature Description

After mapping symbol with ISA string support, we can merge multiple testcases. At the same time, we can increase the coverage.

This patchset:

1. Makes minor tidyings
2. Adds small testing utilities
3. Combines multiple testcases
4. Improves test coverage
   • Add "no required extensions" testcases
   • Uses different registers per operand (as long as allowed)
