r328775) for all platforms. Given that this is the second occurance of this problem it seemed worth fixing this problem in a more generic way. r328775 has been reverted and now a substitution `%linux_static_libstdcplusplus` has been provided. This substitution expands to Clang driver arguments to use a static libstdc++ on Linux and on all other platforms it expands to nothing. The `asan/TestCases/throw_invoke_test.cc` and `test/tsan/static_init6.cc` test cases now use this substitution. rdar://problem/39948818 Differential Revision: https://reviews.llvm.org/D46401 llvm-svn: 332254
