Allow the clang-tools scripts to work with builds in tools such as tools/perf and tools/lib/perf. An example use looks like: ``` $ cd tools/perf $ make CC=clang CXX=clang++ $ ../../scripts/clang-tools/gen_compile_commands.py $ ../../scripts/clang-tools/run-clang-tools.py clang-tidy compile_commands.json -checks=-*,readability-named-parameter Skipping non-C file: 'tools/perf/bench/mem-memcpy-x86-64-asm.S' Skipping non-C file: 'tools/perf/bench/mem-memset-x86-64-asm.S' Skipping non-C file: 'tools/perf/arch/x86/tests/regs_load.S' 8 warnings generated. Suppressed 8 warnings (8 in non-user code). Use -header-filter=.* to display errors from all non-system headers.

This support isn't complete, in particular it doesn't support output directories properly and so fails for tools/lib/bpf, tools/bpf/bpftool and if an output directory is used. v2: Address comments by Nick Desaulniers in patch 3, and add their Reviewed-by to patches 1 and 2.
