[PATCH] D83560: [DebugInfo] Emit DW_OP_implicit_value for Floating point constants

Thanks @MaskRay for pointers. Tried similar approach(slightly different, since expression has to be emitted by a separate streamer owned by `DebugLocDwarfExpression`) to take care of Endianess.

- Temporarily removed `long double` support since IMHO this might require a deeper surgery. Patch reflects the overall skeleton required for suporting `DW_OP_implicit_value`.
- @amyk, is it possible for you to try this patch on PPC targets ? So that we won't end up having surprises.
