plotfi added inline comments.

================
Comment at: clang/lib/Driver/Driver.cpp:2217
   public:
-    typedef llvm::SmallVector<phases::ID, phases::MaxNumberOfPhases> PhasesTy;
+    typedef const std::vector<phases::ID> PhasesTy;
 
----------------

I changed it because it didn't look like you can return a SmallVector, but I 
just changed it back to the old SmallVector function calling style.


================
Comment at: clang/lib/Driver/Driver.cpp:3236
 
-    PL.clear();
-    types::getCompilationPhases(InputType, PL);
+    const std::vector<phases::ID> PL = types::getCompilationPhases(InputType);
+    LastPLSize = PL.size();
----------------

Going to keep the copy. I want to eventually merge getCompilationPhases and 
getFinalPhase into the same function. 


================
Comment at: clang/lib/Driver/Types.cpp:301-303
+  assert(Phases.size() == P.size() && "Invalid size.");
+  for (unsigned i = 0; i < Phases.size(); i++)
+    assert(Phases[i] == P[i] && "Invalid Phase");
----------------

Nice!
