There are following issues with `CFIProgram::parse` code: 1) Invalid CFI opcodes were never tested. And currently a test would fail when the `LLVM_ENABLE_ABI_BREAKING_CHECKS` is enabled. It happens because the `DataExtractor::Cursor C` remains unchecked when the "Invalid extended CFI opcode" error is reported: ``` .eh_frame section at offset 0x1128 address 0x0: Program aborted due to an unhandled Error: Error value was Success. (Note: Success values must still be checked prior to being destroyed). ``` 2) It is impossible to reach the "Invalid primary CFI opcode" error with the current code. There are 3 possible primary opcode values and all of them are handled. Hence this error should be replaced with llvm_unreachable. 3) Errors currently reported are upper-case. This patch refines the code in the `CFIProgram::parse` method to fix all issues mentioned and adds unit tests for all possible invalid extended CFI opcodes.
