The change for PR9190 wasn't quite right. We need to avoid making the
transformation if we can't legally create a build vector of the correct
type. Check that we can make the transformation first, and add a TODO to

Enhance ComputeMaskedBits to know that aligned frameindexes
have their low bits set to zero. This allows us to optimize
out explicit stack alignment code like in stack-align.ll:test4 when
it is redundant.
Doing this causes the code generator to start turning FI+cst into
FI|cst all over the place, which is general goodness (that is the
canonical form) except that various pieces of the code generator
don't handle OR aggressively. Fix this by introducing a new
SelectionDAG::isBaseWithConstantOffset predicate, and using it
in places that are looking for ADD(X,CST). The ARM backend in
particular was missing a lot of addressing mode folding opportunities
around OR.
