Added missed case
The patch missed a case when Compilation object is created during work of
clang based tool, it resulted in fail of the test 'clang-tidy/diagnostic.cpp'.
This addition to the patch add proper checks, hopefully, to all invocations of
'Driver::BuildCompilation'. Small changes are required in clang-tools-extra,
they are tracked by https://reviews.llvm.org/D33173.
