Bug #55826: create table .. select crashes with when
KILL_BAD_DATA is returned
Two problems discovered with the LEAST()/GREATEST()
functions:
1. The check for a null value should happen even
after the second call to val_str() in the args. This is
important because two subsequent calls to the same
Item::val_str() may yield different results.
Fixed by checking for NULL value before dereferencing
the string result.
2. While looping over the arguments and evaluating them
the loop should stop if there was an error evaluating so far
or the statement was killed. Fixed by checking for error
and bailing out.
