The bug was due to a missed case in the detection of whether an index
can be used for loose scan. More precisely, the range optimizer chose
to use loose index scan for queries for which the condition(s) over
an index key part could not be pushed to the index together with the
loose scan.
As a result, loose index scan was selecting the first row in the
index with a given GROUP BY prefix, and was applying the WHERE
clause after that, while it should have inspected all rows with
the given prefix, and apply the WHERE clause to all of them.
The fix detects and skips such cases.

sql/opt_range.cc:
Handle the case when there is no MIN/MAX aggregate function, and a
keypart of the index being considered, that is after the GROUP BY
prefix, is used in the WHERE clause and the condition where it is
used cannot be pushed to the index.
If this is the case, we rule out this index.

The Item_func_if::fix_length_and_dec() function when calculating length of
result doesn't take into account unsigned_flag. But it is taken when
calculating length of temporary field. This result in creating field that
shorter than needed. Due to this, in the reported query 40.0 converted to 9.99.
The function Item_func_if::fix_length_and_dec() now adds 1 to the max_length if
the unsigned_flag isn't set.
