Implement support for module requirements, which indicate the language features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). llvm-svn: 147387

Factor out and unify emission of "module is unavailable" diagnostics. Inspired by post-commit review of r304190. llvm-svn: 304728

Allow a new syntax in a module requires-declaration: requires ! feature The purpose of this is to allow (for instance) the module map for /usr/include to exclude <tgmath.h> and <complex.h> when building in C++ (these headers are instead provided by the C++ standard library in this case, and the glibc C <tgmath.h> header would otherwise try to include <complex.h>, resulting in a module cycle). llvm-svn: 193549

Add cc1 option '-fmodule-feature' to add custom values for 'requires' decls This allows clang-based tools to specify custom features that can be tested by the 'requires' declaration in a module map file. llvm-svn: 227868

[Modules] Allow missing header before a missing requirement And make the module unavailable without breaking any parent modules. If there's a missing requirement after we've already seen a missing header, still update the IsMissingRequiement bit correctly. Also, diagnose missing requirements before missing headers, since the existence of the header is moot if there are missing requirements. llvm-svn: 242055
