I really want to make LLVM easier to build and test, not harder.  The
C++11-pocalypse has been pretty hard on people.  We tried to put together
instructions for building and installing gcc 4.8 locally (not into /usr),
and users were still confused.  Python 2.7 would add one more thing.

I'm comfortable with the status quo of leaving 2.5 as the baseline for old
tools (lit) and allowing 2.7 for new or infrequently used tools
(clang-tidy-diff.py, sort_includes.py).
