Cached conditions are things like (TRUE OR FALSE). They don't actually
add any value to the query and were breaking our working stack trying to
process them.

If a VARCHAR was defined as less than 255 characters and a data via LDI
or INSERT...SELECT was > 127 characters the length field would contain a
negative number.
In 1.0.11 and 1.1.0 this was not a problem because we cast the negative
back again. With MCOL-877 we stoped doing the double-cast. This patch
casts properly the first time.

* COLUMNSTORE_EXTENTS data_size now shows the total size on the highest
segment of an extent file. It also shows 0 bytes if HWM is zero so that
if there is more than one segment it doesn't show 8192 bytes for the
lower segments.
* COMPRESSION_RATIO was missing some data and using compressed data size
instead of file size (which is probably more realistic).

If a CrossEngine step has multiple filters the filters were overwriting
each other. This fix stores the filters as a vector and processes them
in a loop.

DOUBLE typecast was not supported and the failure detection caused a
crash.
This patch adds support for DOUBLE typecast and fixes the crash caused
when a non-supported function is detected as part of an arithmatic.

It is possible to have the columns for a table in a different order
within the system catalog. This causes problems for things like
WriteEngine so this patch sorts the columns based on position for the
system catalog cache.
