[Patch, fortran] PR33733 - ICEs in simplify_transfer

Subject: [Patch, fortran] PR33733 - ICEs in simplify_transfer

:ADDPATCH fortran:

These ICEs came about because gfc_simplify_transfer was trying to
process the source expression for functions of arrays before they
themselves were simplified.  The fix corrects this  by returning null
until the argument is simplified and is no longer EXPR_FUNCTION.

Bootstrapped and regtested on x86_ia64/fc5 - OK for trunk?

Cheers

Paul
