Fixed the lldb_perf_clang.cpp test case to be able to run correctly.

1 - There were some outdated options being passed to clang
2 - There were some bad paths being passed as options
3 - The path to the main.cpp file ("/tmp/main.cpp") was wrong when the tests were being run, now we create a temp file
4 - Added a new ActionType::eNone to do nothing (no continue, step, or kill)
