We've notice that when loops are unrolled there seems to be a limit of 64
subexpressions that can be assigned to registers. In our architecture we've
got a lot more registers available than just 64. Is there some parameter we
can change to the loop unroller that allows more subexpressions to be
assigned to a number of registers beyond 64?
