[patch] Make basic_string::replace forward to different overload

[Jonathan Wakely]

Currently the overload of basic_string::replace taking an
initializer_list forwards to the overload taking two const _Char*
arguments, which does some debug checks, then forwards to the overload
taking a const _Char* and a size_type, which repeats the debug checks.

The initializer_list overload can skip the first step and forward
straight to the second one.

Tested x86_64-linux, committed to trunk.
