… instance which may differ from the one in the ASTContext As per swiftlang/swift#65930, Swift compiler's built-in Clang instance may require to perform type-checking against one OS version and compilation/code-generation against an earlier version. This change allows Swift to configure it's built-in Clang code-generator with a custom 'TargetInfo'. Part of rdar://113712186

…form version Similarly to 'CheckAvailability' and 'getAvailability', set 'Decl::isWeakImported' to allow querying using an external target platform version. In #7916 we have added support for configuring 'clang::CodeGenerator' with a differently-versioned target info, and this change adopts the code generator's target info in order to also determine weakly-imported linkage on declarations during code-gen. Before this change, they were relying on the 'ASTContext' to specify the target info, which may differ from code-gen's.
