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

[Tim Renouf via Phabricator via llvm-commits]

@foad pointed out that this fix is wrong. TLI saying pow() is not supported means if we find a call to a function called pow() then we don't know its semantics. So I will push a revised fix.
