[PATCH] D91120: [DAGCombine][PowerPC] Fold negated abs to avoid generating `select_cc`

[Sanjay Patel via Phabricator via llvm-commits]

Note that we are planning to canonicalize IR to the abs() intrinsic - D87188 <https://reviews.llvm.org/D87188>.
Assuming that comes through relatively soon (cc @nikic), should we hold off adding what would probably become dead code in the backend?
