Tested on x86-64.
Note this did not preserve semantics, though ultimately I think the problem is
a specific to the c6x port and the old semantics were buggy IMHO. I haven't
dug deeply, but I suspect the old code returned NULL_RTX for this because the
call operand wasn't a MEM.
It also causes an ICE building glibc for s390-linux-gnu.

Yea, looks like the same basic signature.
