Nikolai Kosjar 0498fb68ff C++: Revert lookup to 3.4.2 
...which was least buggy.

The bugs fixed by the changes we revert here (highlighting/completion
for code involving templates) were minor compared to ones we currently
have. Those bugs will be addressed by the clang code model anyway.

Relevant commits were collected via:

  $ cd ${QTC}/src/libs/cplusplus
  $ git log \
   --no-merges \
   --format=oneline \
   v3.4.2..HEAD \
   -- LookupContext.* ResolveExpression.* TypeResolver.* TypeOfExpression.* \
      ../../plugins/cpptools/cppcompletion_test.cpp

From this list the following were skipped due to irrelevance:

  88c5b47e53 # CppTools: Minor cleanup in completion tests
  e5255a1f5c # CppTools: Add a test for ObjC not replacing dot with arrow
  5b12c8d63a # CppTools: Support ObjC in member access operator tests
  9fef4fb9ca # CPlusPlus: Fix warnings about overriding visit(...) methods

There were only minor conflicts while reverting those.

This changes touches so many files because there were quite some
cleanups and renames after the 3.4.2 release.
