Decouple dllexport/dllimport from linkage Representing dllexport/dllimport as distinct linkage types prevents using these attributes on templates and inline functions. Instead of introducing further mixed linkage types to include linkonce and weak ODR, the old import/export linkage types are replaced with a new separate visibility-like specifier: define available_externally dllimport void @f() {} @Var = dllexport global i32 1, align 4 Linkage for dllexported globals and functions is now equal to their linkage without dllexport. Imported globals and functions must be either declarations with external linkage, or definitions with AvailableExternallyLinkage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199218 91177308-0d34-0410-b5e6-96231b3b80d8

Delete -std-compile-opts. These days -std-compile-opts was just a silly alias for -O3. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219951 91177308-0d34-0410-b5e6-96231b3b80d8
