MDEV-5581: Server crashes in in JOIN::prepare on 2nd execution of PS with materialization+semijoin
- The problem was that JOIN::prepare() tried to set TABLE::maybe_null
for a table in join. Non-merged semi-join tables 1) are present as
join's base tables on second EXECUTE, but 2) do not yet have a TABLE
object.
Worked around the problem by putting mixed_implicit_grouping into JOIN
object, and then passing it to JTBM tables in setup_jtbm_semi_joins().
