Fix EXTRACT_LAST_REDUCTION segfault

This code: /* Make sure we don't accidentally use the old condition. */ cond_expr = NULL_TREE; was misplaced, since it triggered even when we needed to force the original unmodified cond_expr into a mask temporary and then invert it. 2019-12-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-stmts.c (vectorizable_condition): Only nullify cond_expr if we've created a new condition. Don't nullify it if we've decided to keep it and then invert the result. gcc/testsuite/ * gcc.dg/vect/vect-cond-reduc-6.c: New test. From-SVN: r279804
