From: Eric Botcazou <ebotca...@adacore.com>
The change causes more temporaries to be created at call sites for unaligned
actual parameters, thus revealing that the machinery does not properly deal
with unconstrained nominal subtypes for them.

* gcc-interface/trans.cc (create_temporary): Deal with types whose
size is self-referential by allocating the maximum size.
Tested on x86_64-pc-linux-gnu, committed on master.
