  -----------
  ADT: Switch to a raw pointer for DoubleAPFloat::Floats.

In order for the union APFloat::Storage to permit access to the
semantics field when another union member is stored there, all members
of Storage must be standard layout. This is not necessarily the case
for DoubleAPFloat which may be non-standard layout because there is no
requirement that its std::unique_ptr member is standard layout. Fix this
by converting Floats to a raw pointer.
