Archive of RTL dumps of failing testcase built with "-Os"

I spent some time looking through the RTL dump.  It looks like the stack
references first show up in 194r.split2, but I couldn't understand enough of
what I was looking at to match it up with the assembly output or figure out
where the CFI information went wrong.

I've attached a tar.gz of the RTL dumps in case that helps isolate the issue.

Cheers,
