Bug#836397: clang-4.0: Create clang-tools-4.0 and move the various clang tools into it

[Sylvestre Ledru]

Package: clang-4.0
Severity: wishlist

We have more and more tools generated at part of clang-tools-extra.
As their number is growing and they are not necessary to build C/C++, we should move them into a dedicated packages like clang-tools-4.0

For example, all of these binaries could be moved into this package. 
usr/bin/clang-check-4.0
usr/bin/clang-apply-replacements-4.0
usr/bin/clang-query-4.0
usr/bin/clang-rename-4.0
usr/bin/sancov-4.0
usr/bin/modularize-4.0
usr/bin/c-index-test-4.0
usr/bin/clang-offload-bundler-4.0
usr/bin/clang-reorder-fields-4.0
usr/bin/find-all-symbols-4.0
usr/bin/clang-include-fixer-4.0


We could also create a clang-scan-build-4.0 packages with:
usr/bin/scan-build-4.0
usr/bin/scan-view-4.0
