SVE fallout from PR90006 

2019-04-08  Richard Sandiford  <richard.sandiford@arm.com>

gcc/
	* tree-vect-data-refs.c (vect_get_smallest_scalar_type): Always
	use gimple_expr_type for load and store calls.  Skip over the
	condition argument in a conditional internal function.
	Protect use of TREE_INT_CST_LOW.
