only look at the first values for first()
...
Since we set up the aggregate queries so that iterator is ordered,
we only need to look at the first value. This cuts about 10 seconds
off a large single series query running first.

During first() and last(), break any tie by value
...
If 2 or more points during this map-and-reduce share the same timestamp,
the tie is broken by looking at the value. This ensures that these
functions operate in a deterministic manner.
This solution due to @jwilder

Optimize the very inner loop of cursor iteration
...
This change moves tracking of next timestamp and values to simple
slices, as performance measurement showed that Peek() on TagSet cursors
was a huge performance drain. There is much more that can be done here,
but with this in place query performance has been restored to 0.9.1
levels.
This change also uses -1 to indicate that no value is available for a
given timestamp.

Fix style issues with else

In go it's better to just continue flow without "else", if it is return in
