3506         Also use reload_reg_rtx_reaches_end_p when reading new_spill_reg_store
3507         for non-spill reload registers.

3512         * tree-vectorizer.h (vect_is_simple_use): Add an argument.
3513         (vect_is_simple_use_1): Likewise.
3514         * tree-vect-loop.c (vectorizable_reduction): Update calls
3515         to vect_is_simple_use_1 and vect_is_simple_use.

3523         (vect_is_simple_cond): Add an argument, pass it to
3524         vect_is_simple_use_1.
3525         (vectorizable_condition): Update calls to vect_is_simple_cond,

3527         (vect_is_simple_use): Add an argument, the statement in which
3528         OPERAND is used.  Check that if OPERAND's def stmt is a double
