    expand: Fix up ICE on VCE from _Complex types to _BitInt [PR117458]

    extract_bit_field can't handle extraction of non-mode precision
    from complex mode operands which don't live in memory, e.g. gen_lowpart
    crashes on those.
    The following patch in that case defers the extract_bit_field call
    until op0 is forced into memory.

            * expr.cc (expand_expr_real_1) <case VIEW_CONVERT_EXPR>: Don't
            call extract_bit_field if op0 has complex mode and isn't a MEM,
            instead first force op0 into memory and then call
extract_bit_field.
