Reverting Richard's patch to function.c eliminates the regression.
The regression also affects hppa-unknown-linux if I disable the kernel
unaligned handler.
The 32-bit PA ABI has rather special requirements for passing 5-7 byte
structs. See the comment in function_arg in pa.c. I believe the fail
in test5 is caused by trying to pass a 5 byte struct.
