ARM: improve diagnostics for .word directive

If a complex expression was passed to the .word directive and the first part of
the directive failed to parse, a secondary diagnostic would be produced that
would clutter the error diagnostics.  Improve the diagnostics by consuming the
remainder of the statement.
