[modules] When using -E, we may try to merge decls despite having no Sema object. In such a case, use the TU's DC for merging global decls rather than giving up when we find there is no TU scope. Ultimately, we should probably avoid all loading of decls when preprocessing, but there are other reasonable use cases for loading an AST file with no Sema object for which this is the right thing. llvm-svn: 228234 2015-02-05 07:37:59 +08:00			`module fwd { header "fwd.h" export * }`
When preprocessing with -frewrite-imports and -fmodule-file=, do not pass all modules to preprocessing of nested .pcm files. Making those module files available results in loading more .pcm files than necessary, and potentially in misbehavior if a module makes itself visible during its own compilation (as parts of that module that have not yet been processed would then become visible). llvm-svn: 306320 2017-06-27 03:39:25 +08:00			`module file { header "file.h" header "file2.h" header "other.h" export * }`
[modules] When we #include a local submodule header that we've already built, and it has an include guard, produce callbacks for a module import, not for a skipped non-modular header. Fixes -E output when preprocessing a module to list these cases as a module import, rather than suppressing the #include and losing the import side effect. llvm-svn: 304183 2017-05-30 10:03:19 +08:00			`module nested {`
