[TRAFODION-2047] add support of SQL syntax INTERSECT
support of SQL syntax INTERSECT, INTERSECT DISTINCT
not able to support INTERSECT ALL, which will raise an error.
TPCDS quries only need INTERSECT, and the semantics is same, while two
child input of INTERSECT must have same number of columns and in same order and
each column type must be matching.
Also a minor change to TM Makefile to include log4cxx header file path, if
log4cxx is not installed into system include path.
