[Patch, fortran] PR31620 - [4.3 regression] Zeroing one component of array of derived types zeros the whole structure.

[Paul Richard Thomas]

:ADDPATCH fortran:

This rather bad regression is due to all the components of an array of
derived types being part of the array in an assignment of zero to one
component.  The patch is self-explanatory and the testcase is the
reporter's.

Regtested on x86_ia64 - OK for trunk?
