provide a more-specific, remappable diagnostic when takin the address
of such a temporary.

If there exists a use of a build_vector that's the bitwise complement of the mask,
then transform the node to
(and (xor x, (build_vector -1,-1,-1,-1)), (build_vector ~c1,~c2,~c3,~c4)).

Since this transformation is only useful when 1) the given build_vector will
become a load from constpool, and 2) (and (xor x -1), y) matches to a single
instruction, I decided this is appropriate as a x86 specific transformation.

Add support for emitting non-temporal stores for DAGs marked
non-temporal.  Fix from r96241 for botched encoding of MOVNTDQ.

Add documentation for !nontemporal metadata.

Add a simpler movnt testcase.

ISel. Remove definitions of CarryDefIsUnused and CarryDefIsUsed since they are
no longer used anywhere.

They won't work with the new ISel mechanism, as Requires predicates are no
longer allowed to reference the node being selected. Moving the predicate to
the patterns instead solves the problem.

This patch handles ARM mode. Thumb2 will follow.

now cope with the destruction of types named as dependent templates,
e.g.,

  y->template Y<T>::~Y()

Nominally, we implement C++0x [basic.lookup.qual]p6. However, we don't
follow the letter of the standard here because that would fail to
parse

  template<typename T, typename U>
  X0<T, U>::~X0() { }

properly. The problem is captured in core issue 339, which gives some
(but not enough!) guidance. I expect to revisit this code when the
resolution of 339 is clear, and/or we start capturing better source
information for DeclarationNames.

Fixes PR6152.
