  Changed paths:
    M llvm/cmake/modules/GetErrcMessages.cmake

  Log Message:
  -----------
  [test] Make sure the test program in GetErrcMessages.cmake exits normally.

If for some reason the test program does not exit normally it'd currently lead to a false positive and it's stdout output being assigned to the output variable.

Instead, check the test program exited normally before assigning the process output to the out variable.
