Revert "Remove troublesome Asserts in cost_mergejoin()."

Browse Source 
This reverts commit ff68b256a5.
The recent change to use -fexcess-precision=standard should make those
Asserts safe, and does fix a test case that formerly crashed for me,
so I think there's no need to have a cross-version difference in the
code here.
