As I suggested yesterday on the libstdc++ list, this adds an overload
for string and vector iterators to extract a raw pointer and re-use
the _Compiler<const C*,...> specialization, so that std::regex(".")
and std::regex(std::string(".")) and std::regex(std::vector<char>(1,
'.')) only instantiate _Compiler<It,Tr> once.

        * include/bits/regex_compiler.h (__detail::__compile_nfa): Overload
        so that std::basic_string<C> and std::vector<C> iterators dispatch to
        the const C* compiler.

Tested x86_64-linux, committed to trunk.
