Attached patch is the second take on PR fortran/28163. Instead of
generating calls to libgfortran copy_string, we emit the code
directly. As my previous mails showed, the size impact is minimal
since the code emitted is small. There is a 27%
performance impact of this on at least one of the polyhedron
benchmarks, aermod.

Bootstrapped and regtested on i686-linux. OK for mainline?
