middle-end/100582 - fix array_at_struct_end_p for vector indexing

Vector indexing leaves us with ARRAY_REFs of VIEW_CONVERT_EXPRs,
sth which array_at_struct_end_p considers a array-at-struct-end
even when there's an underlying decl visible.  The following fixes
the latter.

PR middle-end/100582
* tree.c (array_at_struct_end_p): Get to the base of the
reference before looking for the underlying decl.

* gcc.target/i386/pr100582.c: New testcase.
