Unused Standard Library Headers #2
Description
clangd IncludeCleaner has experimental support for standard library headers behind a --include-cleaner-stdlib, but suggest_include_changes.py won't be able to fully support it at the moment since it can't map from includes like #include <string> to buildtools/third_party/libc++/trunk/include/string, so it won't be able to match up the edge size from include analysis output.
Consider mapping #include \<(.*)\> lines to buildtools/third_party/libc++/trunk/include/(.*), that might cover most cases and be "good enough" for these purposes.
