[PATCH] D24011: [ConstantFold] Add a flag for ppc_fp128 constant folding, since APFloat doesn't support double-double semantic

[Eric Christopher via llvm-commits]

Somewhat sadly I think the best move forward is going to be getting ppc_fp128 support in APFloat. Moving forward with IEEE754r support in Power9 it might make sense to switch the platform to support that by default, but we're not there yet.
