Setting Field::field_index for Virtual_tmp_table fields

Browse Source 
Virtial_tmp_table did not set the "field_index" member for its Fields.
Fixing Virtual_tmp_table::add() to set "field_index" to the Field's ordinal position
inside the table, like a normal TABLE does, for consistency.

Although, this flaw did not seem to cause any bugs, having field_index properly
set is helpful for debugging purposes.
