Insert a new stmt (INIT_STMT) that initializes a new vector variable with
the vector elements of VECTOR_VAR. Place the initialization at BSI if it
is not NULL. Otherwise, place the initialization at the loop preheader.
Insert a new stmt (INIT_STMT) that initializes a new variable of type
TYPE with the value VAL. If TYPE is a vector type and VAL does not have
vector type a vector with all elements equal to VAL is created first.
Place the initialization at BSI if it is not NULL. Otherwise, place the
initialization at the loop preheader.
Return the DEF of INIT_STMT.
It will be used in the vectorization of STMT. */
