[PATCH] D68231: [SLC] Allow llvm.pow(x,2.0) -> x*x etc even if no pow() lib func

[Eli Friedman via Phabricator via llvm-commits]

I don't understand what the check is supposed to be doing in the first place.  If we're in LibCallSimplifier::optimizePow, we've already checked that the call is actually calling a function with the right semantics, not just the name.
