* Speed up String first/last aggregators when folding isn't needed.

Examines the value column, and disables fold checking via a needsFoldCheck
flag if that column can't possibly contain SerializableLongStringPairs. This
is helpful because it avoids calling getObject on the value selector when
unnecessary; say, because the time selector didn't yield an earlier or later
value.

* PR comments.

* Move fastLooseChop to StringUtils.
