Daniel Cederman 0fa121db2e [Sparc] Use ANDN instead of AND if constant can be encoded more efficiently 
Summary:
In the case of (and reg, constant) or (or reg, constant), it can be
beneficial to use a ANDNrr/ORNrr instruction instead of ANDrr/ORrr,
if the complement of the constant can be encoded using a single SETHI
instruction instead of a SETHI/ORri pair.

If the constant has more than one use, it is probably better to keep it
in its original form.
