Looking for a review of the LTO changes to switch TREE_NO_WARNING to
the suppress_warning() API.
Hmm, since

Since match and simplify does not have all of the inverted
comparison patterns, it make sense to just have
phi-opt try to do the inversion and try match and simplify again.
OK? Bootstrapped and tested on

Since match_simplify_replacement uses gimple_simplify, there is a new
ssa name created sometimes and then we go and replace the phi edge with
this new ssa name, the range information on the phi is lost.

I had missed this when wrote the patch which allowed the
gimple to be moved from inside the conditional as it. It
was also missed in the review. Anyways the range information
needs to be reset for the moved gimple

To make things slightly easiler to convert fold_cond_expr_with_comparison
over to match.pd, expanding the arg0 argument into 3 different arguments
is done. Also this was simple because we don't use arg0 after
