Avoid an unnecessary key comparison when doing an indexed lookup against an equality constraint. (check-in: d741e1ccdc user: drh tags: trunk)

Test changes: Omit numindex1.test from valgrind, since valgrind uses a none-standard floating-point processor which gives inconsistent answers. Run one releasetest.tcl module using LONGDOUBLE_TYPE=double. (check-in: d421efbf9a user: drh tags: trunk)
