Hi, I have been very interested in loop fusion recently. I found that
both LLVM and icc have implemented this optimization. I also noticed
that gcc does not seem to implement it.

I would like to ask if gcc have any plans to implement this
optimization? In addition, I also found that there is a function
called `fuse_loop` in gcc/gimple-loop-jam.cc. Can it achieve the
purpose of loop fusion?
