[clang][Driver] Add -fintegrate-as to debug-pass-structure test

CGProfilePass is not always on, it will be disabled when using
non-intergrated assemblers.

  // Only enable CGProfilePass when using integrated assembler, since
  // non-integrated assemblers don't recognize .cgprofile section.
  PMBuilder.CallGraphProfile = !CodeGenOpts.DisableIntegratedAS;

Add -fintegrate-as to make sure the output don't rely on the platform default.
