Robert Haas af025eed53 Add combine functions for various floating-point aggregates.
This allows parallel aggregation to use them.  It may seem surprising
that we use float8_combine for both float4_accum and float8_accum
transition functions, but that's because those functions differ only
in the type of the non-transition-state argument.
