We can do that now as QtC moved to c++17 in master

This is not supported. People must use the content of the installation
directory instead.
This reduces complexity of qbs' own project files.

This will enable us to simplify some of our templates.
Qt Creator requires C++14 as well, so we won't break it.

Takes two qbs repo states, runs callgrind and massif on different phases
of the build process for each of them and informs the user of the
relative performance of these operations.
I suggest running this tool before committing anything that could
conceivably impact performance. Note that we have similar regression
detection functionality on our build machines, but it's better to spot
such problems before pushing a change.
Example output (for commits 04df1532c4 and f53d724eec building qbs itself):
