9da058bb5c Use OP_Sort rather than OP_Rewind in order to sort the content of a new 
index on the CREATE INDEX statement.  Add an ALWAYS() to the merge sort
logic to document an unreachable branch.

9d71142c9c When opening a temporary file to use in a merge-sort, pass SQLITE_OPEN_TEMP_JOURNAL instead of SQLITE_OPEN_TEMP_DB. This is a better fit, as merge-sort files are written and read sequentially like journal files.

directories.
