[Bug rtl-optimization/36712] Inefficient loop unrolling

[drow at gcc dot gnu dot org]

I really would like to see this submitted - at least as a starting point for
discussion.  You don't need to do anything different than for a small patch; if
you've missed any steps, a reviewer will tell you.

Another problem I noticed is that if RTL loop unrolling unrolls a loop, only
the first iteration will use auto-inc patterns.  This leads to silly omissions
in the assembly.
