Explain how doing COMPUTE INCREMENTAL STATS for the first time
starts over and discards any previous stats from COMPUTE STATS.
As a consequence, moved some wording and examples into
impala_common.xml so that content could be used in
multiple places. Also made a new subtopic on the "Partitioning"
page because I saw COMPUTE INCREMENTAL STATS wasn't mentioned
there.

Switched the example for Infinity and NaN in the
impala.common file so it will be correct every-
where this example is used in the Impala
documentation. Instead of saying, "pow(-1, 0.5)
returns infinity and 1/0 returns NaN" it has
been corrected to "1/0 returns infinity and
pow(-1, 0.5) returns NaN."

Add CLUSTERED hint.
Update hint syntax in INSERT topic.
Also modernize the hint syntax as shown under INSERT
to include the -- and /* */ formats also. List
the [] style last since it is the least-preferred
option.
Switch to preferring /* */ syntax for hints
instead of using the [ ] notation by default.
Finally, take out references to the SORTBY hint because
it didn't actually make it in. Intent for future is to have a way
to get this behavior without using a hint.
