Log:
S/390: Fix vecinit expansion.

The fallback routine in the S/390 vecinit expander did not check
whether each of the initializer elements is a proper general_operand.
Since revision r236582 the expander is invoked also with e.g. symbol
refs with an odd addend resulting in invalid insns.

Fixed by forcing the element into a register in such cases.
