    Test passing structs by value

exposed a problem on the hppa linux port:

Running ../../libffi/testsuite/ ...
FAIL: -W -Wall -Wno-psabi -O0 execution test
FAIL: -W -Wall -Wno-psabi -O2 execution test

Currently, the code assumes that structs larger than 8 bytes are passed by hidden reference.

Probably, this has broken builds of python_cffi, etc.
