Tim Northover a5eeb9da05 SelectionDAG: create correct BooleanContent constants ...

Occasionally DAGCombiner can spot that a SETCC operation is completely
redundant and reduce it to "all true" or "all false". If this happens to a
vector, the value produced has to take account of what a normal comparison
would have produced, which may be an all-1s bitmask.

The fix in SelectionDAG.cpp is tested, however, as far as I can see the code in
TargetLowering.cpp is possibly unreachable and almost certainly irrelevant when
triggered so there are no tests. However, I believe it's still clearly the
right change and may save someone else some hassle if it suddenly becomes
reachable. So I'm doing it anyway.

Remove an over-zealous assertion. A pointer type could be illegal if the target is prepared to custom-legalize pointer operands. This assertion was evaluated before the target would have a chance to do so, making it impossible.
