[RISCV] Add tests showing incorrect BUILD_VECTOR lowering
These tests both use vector constants misidentified as VID sequences.
Because the initial run of elements has a zero step, the elements are
skipped until such a step can be identified. The bug is that the skipped
elements are never validated, even though the computed step is
incompatible across the entire sequence.
A fix will follow in a subseqeuent patch.
