    Remove assert from set_nonzero_bits.
    
    The assert removed by this patch was there to keep users from passing
    masks of incompatible types.  The self tests are passing host wide
    ints down (set_nonzero_bits (-1)), which seem to be 32 bits, whereas
    some embedded targets have integer_type_node's of 16-bits.  This is
    causing problems in m32c-elf, among others.
    
    I suppose there's no harm in passing a 32-bit mask, because
    set_nonzero_bits calls wide_int::from() to convert the mask to the
    appropriate type.  So we can remove the assert.
    
    gcc/ChangeLog:
    
            * value-range.cc (irange::set_nonzero_bits): Remove assert.
