Optimize truncating a basic_string

* include/bits/basic_string.h [_GLIBCXX_USE_CXX11_ABI]
(basic_string::erase(size_type, size_type)): Add fast path for
truncating the string, by calling _M_set_length directly.
(basic_string::erase(__const_iterator, __const_iterator)): Likewise.
* include/bits/basic_string.tcc [_GLIBCXX_USE_CXX11_ABI]
(basic_string::resize(size_type, _CharT)): Likewise.
