Overall: (6 cases)

- Test method
  * Add cases/soft-inj/panic_ucr/cases.sh into configuration file, and invoke
    a test driver on it.
- Common
  * Test script of test cases in this file can be found in
    cases/soft-inj/panic_ucr/cases.sh

1. s0_ar1

- Objective:
  * Test MSR read logic of MCE handler
