Split string capacity test into two parts and mark one part as UNSUPPORTED when using sanitizers. The test is split such that: - max_size.pass.cpp tests that string::resize() fails to allocator for max_size and max_size -1 - over_max_size.pass.cpp tests that string::resize() throws a length error for max_size + 1 The test was split into two because max_size.pass.cpp cannot pass with sanitizers but over_max_size.pass.cpp can. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@221969 91177308-0d34-0410-b5e6-96231b3b80d8
