ccd794a676 Add remerge_sort_lowered_memory_bytes_ratio setting 
Sometimes default ratio is not good enough (2), since it depends on lots
of factors:
- size of LIMIT
- max_memory_usage
- ...

So add a separate setting for it.

But note that it make sense to set
remerge_sort_lowered_memory_bytes_ratio only in range (1, 2]

Since <= 1 will just use more CPU, and > 2 will use more RAM and will
unlikely be faster.
