When optimizing a logical arithmetic operation, which operands are both
comparisons using different operators, make sure to generate an insn
with the correct mode.
This means that constructs like
if (c != -1 & i < 9999)
and
if ((i<=7) | (value != 0))
as found in transfig and teTeX, respectively, will now compile with
optimization.
Note the single & or | in these constructs - this kind is rare enough for
this bug to have remained unnoticed until now...
