* fold-const.c (make_bit_field_ref): Change bitpos and bitsize
arguments to HOST_WIDE_INT.  If type has different signedness
than unsignedp or different precision from bitsize, create
the right type for BIT_FIELD_REF and cast to type.
(fold_truthop): Change first_bit and end_bit to HOST_WIDE_INT.

The bug reappeared on the 4.3 branch.
It remains fixed on mainline, though.
So no status change since it's not a regression.
