Issue #2531: Make float-to-decimal comparisons return correct results.
Float to decimal comparison operations now return a result based on
the numeric values of the operands. Decimal.__hash__ has also been
fixed so that Decimal and float values that compare equal have equal
hash value.

Issue #7279: Make Decimal('nan') hashable. Decimal('snan') remains unhashable.
Also rewrite the Decimal __hash__ method so that it doesn't rely on
float('inf') being valid: float('inf') could raise an exception on
platforms not using IEEE 754 arithmetic.

+- Issue #7279: Comparisons involving a Decimal signaling NaN now
+ signal InvalidOperation instead of returning False. (Comparisons
+ involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
+ are now hashable; Decimal signaling NaNs remain unhashable.
+
+- Issue #2531: Comparison operations between floats and Decimal
+ instances now return a result based on the numeric values of the
+ operands; previously they returned an arbitrary result based on
+ the relative ordering of id(float) and id(Decimal).
