patch to put debug statements in cselib.c

I still cannot reproduce the failure.  I have built cross compilers on linux
with GCC 4.9 and GCC 5.2 and I have built the cross compiler in both 32 and 64
bit modes.

Here is a patch file to apply to cselib.c, Could you try applying it, building
GCC, running the test program, and sending me the output.  Maybe comparing the
output you get with what I get will help me understand what is going on.  This
patch includes the earlier changes I had suggested so you should remove those
before applying this patch or they will conflict.
