[Committed] PR middle-end/102029: Stricter typing in LSHIFT_EXPR sign folding.
My sincere apologies to everyone (again). As diagnosed by
Jakub Jelinek, my recent patch to fold the signedness of LSHIFT_EXPR
needs to be careful not to attempt transforming a left shift in an
integer type into an invalid left shift of a pointer type.
