// Tests for -fprofile-generate and -fprofile-use flag compatibility. These two
// flags behave similarly to their GCC counterparts:

// -fprofile-use Uses the profile file ./default.profdata
// -fprofile-use=<dir> Uses the profile file <dir>/default.profdata
// -fprofile-use=<dir>/file Uses the profile file <dir>/file
