This is a follow up to #112015 and it reduces the unnecessary duplication of source locations further. We do not need to allocate source location space in the serialized PCMs for module maps used only to find textual headers. Those module maps are never referenced from anywhere in the serialized ASTs and are re-read in other compilations. This change should not affect correctness of Clang compilations or clang-scan-deps in any way. We do need the InputFile entry in the serialized AST because clang-scan-deps relies on it. The previous patch introduced a mechanism to do exactly that. We have found that to finally remove any duplication of module maps we use internally in our build system.
