[patch] string::_M_set_lengt_and_sharable clean up

[Paolo Carlini]

Hi,

this is clean up originally conceived by Benjamin, that I have
further extended to include _M_set_sharable and thus _S_create
too. Probably, will also make easier other rearrangments ...

Tested x86-linux for now, I will further test and commit.

Paolo.
