Fix constant-folding for Integer shifts
In this patch
commit 869f69fd4a78371c221e6d9abd69a71440a4679a

Guarding against silly shifts
we deal with silly shifts like (Sll 1 9223372036854775807). But
I only dealt with primops that Int# and Word#.
Alas, the same problem affects shifts of Integer, as Trac #15673
showed. Fortunately, the problem is easy to fix.
