+==================== Work084, patch #3:
+
+Replace UNSPEC with RTL code for extendditi2.
+
+When I submitted my patch on March 12th for extendditi2, Segher wished I
+had removed the use of the UNSPEC for the vextsd2q instruction.  This
+patch rewrites extendditi2_vector to use VEC_SELECT rather than UNSPEC.
