While doing this, I also found a few tests that were either clearly incorrect (e.g. testing the wrong function) or that lacked basic test coverage like testing std::string itself (e.g. the test was only checking std::basic_string with a custom allocator). In these cases, I did a few conservative drive-by changes. Differential Revision: https://reviews.llvm.org/D140550 Co-authored-by: Brendan Emery <brendan.emery@esrlabs.com>
