[Patch, fortran] PR38915 - wrong results for structure assignment of character components when left and right sides overlap

[Paul Richard Thomas]

The attached is a belt-and-braces approach to the string length of
temporaries getting lost in simple assignments of character derived
type components.

Bootstrapped and regtested on FC9/x86_64 - OK for 4.5?
