program: Shrink and rename SaturateMode field to Saturate.
It was 2 bits to accommodate SATURATE_PLUS_MINUS_ONE (removed by commit
09b566e1). A similar change was made to TGSI recently in commit
e1c4e8aa.
Reducing the size from 2 bits to 1 reduces the size of the bit fields
from 17 bits to 16, which is a much nicer number.
