Fixed bug#15950: NOW() optimized away in VIEWs
This bug is a side-effect of bug fix #16377. NOW() is optimized in
BETWEEN to integer constants to speed up query execution. When view is being
created it saves already modified query and thus becomes wrong.
The agg_cmp_type() function now substitutes constant result DATE/TIME functions
for their results only if the current query isn't CREATE VIEW or SHOW CREATE
VIEW.
