1.4.1 fix gcc build (#9)

* make specialized compound key scan state for eq compares, specialized scan using ARTKey::Concat

* table scan:

rebind projected columns in ALL index exprs
do not bail out early if more than one index expr
hook up composite key scan

* copy index expressions before rewriting column refs

* simplify filter expression storage index bindings (just reuse the ones we made earlier), fix single-ref-per-expr predicate to correctly walk expr tree and yank refs (allowing nesting in fns, etc)

* add test, bail out for eg composite query with IN () list

* do not do index scan if there are other non index filters in the predicate (fix shutdown_create_index.test)

* tryscanindex sanity check: indexed_columns / art column ids may not need remapping if the scan is not a view scan

* tryscanindex: do column matching first, to use possibly rebound matches in both sanity check and index expr rebinding
add test for this scenario

* tryscanindex: fix direct match lookup, range check vec access

* compile on gcc
