enable live condition vectorization

This removes a check preventing vectorization of live results of
vectorized conditions.

* tree-vect-stmts.c (vectorizable_condition): Allow
STMT_VINFO_LIVE_P stmts.

* gcc.dg/vect/vect-cond-13.c: New testcase.
* gcc.target/i386/pr87007-4.c: Adjust.
* gcc.target/i386/pr87007-5.c: Likewise.
