Ensure that btree sort ordering functions and boolean comparison operators
give consistent results for all datatypes. Types float4, float8, and numeric were broken for NaN values; abstime, timestamp, and interval were broken for INVALID values; timetz was just plain broken (some possible pairs of values were neither < nor = nor >). Also clean up text, bpchar, varchar, and bit/varbit to eliminate duplicate code and thereby reduce the probability of similar inconsistencies arising in the future.
