Fixed LP BUG#652727 and LP BUG#643424.
The fixes for #643424 was part of the fix for #652727, that's why both
fixes are pushed together.
- The cause for #643424 was the improper use of get_partial_join_cost(),
which assumed that the 'n_tables' parameter was the upper bound for
query plan node indexes.
Fixed by generalizing get_partial_join_cost() as a method that computes
the cost of any partial join.
- The cause of #652727 was that JOIN::choose_subquery_plan() incorrectly
deleted the contents of the old keyuse array in the cases when an injected
plan would not provide more key accesses, and reoptimization was not actually
performed.
