Summary: Currently, libc++'s `<stdexcept>` doesn't play nice with `vcruntime`. Specifically: * `logic_error` and `runtime_error` have a different layout. * libc++'s `logic_error` and `runtime_error` override `what()` but `vcruntime` does not. * `vcruntime` uses weak vtables for `<stdexcept>` types. * libc++'s `<stdexcept>` constructors and assignment operators may have different manglings than `vcruntimes`. This patch makes libc++'s declarations in `<stdexcept>` match those provided by MSVC's STL as closely as possible. If MSVC doesn't declare a special member, then neither do we. This ensures that the implicit definitions have the same linkage, visibility, triviality, and noexcept-ness.
