[patch] std::string::operator[] extension in debug mode

Subject: [patch] std::string::operator[] extension in debug mode

As discussed this makes debug mode support the v3 extension allowing
s[s.size()] on non-const strings.  This fixes these FAILs when the tests
are run in debug mode:
FAIL: 21_strings/basic_string/element_access/char/empty.cc execution test
FAIL: 21_strings/basic_string/element_access/wchar_t/empty.cc execution test

I decided to order the assertions this way so that in non-pedantic mode
pos > size() will produce an error message that shows the extension
would work.

	* include/bits/basic_string.h (operator[]): Allow s[s.size()] in
        debug mode, but not pedantic mode.

OK for mainline and 4.0 ?
