Depending on how long it takes my _FloatN / _FloatNx patch to get
reviewed, it might be better to avoid adding the built-in functions as
target-specific on trunk. Adding them as architecture-independent would
be extremely straightforward once the support for the types is there, and
then the architecture-specific versions would only be needed for GCC 6.
(The insn patterns and tests would still be relevant for trunk.)
