Log:
Fix code order in tree-sra.c:create_access

If get_ref_base_and_extent returns poly_int offsets or sizes,
tree-sra.c:create_access prevents SRA from being applied to the base.
However, we haven't verified by that point that we have a valid base
to disqualify.

This originally led to an ICE on the attached testcase, but it
no longer triggers there after the introduction of IPA SRA.

	* tree-sra.c (create_access): Delay disqualifying the base
