Can you add a few options and report back the reports?

You can add -ftime-report to the command line to let the compiler dump
a report about how much time it spent in different parts of the compiler.

With your observation about cselib, I suspect this is another issue with
the scalability of var-tracking. Can you try with -g -fno-var-tracking?
