fp-ieee: IEEE 754 operations for floating-point types

This library provides IEEE 754-compliant operations, including

fusedMultiplyAdd.
correctly-rounding versions of fromInteger.
realFloatToFrac, which correctly handles signed zeros, infinities, and NaNs (unlike realToFrac).

Some operations (e.g. fusedMultiplyAdd) can make use of the native instruction in the architecture.

For non-native targets, "Pure Haskell" mode is supported via a package flag.

Most operations require only RealFloat constraint, but RealFloatNaN is needed by some operations that access the sign and payload of NaNs.
