f00e74f4d6 Turn LegalizeTypes back off again for the moment:
it is breaking Darwin bootstrap due to missing
functionality.

was turned up by some new SelectionDAG assertion checks that I'm
working on.

05c397d52a Reorder methods alphabetically. No functionality change.
While this is not a wonderful organizing principle, it
does make it easy to find routines, and clear where to
insert new ones.

c07e6e53f7 LegalizeTypes support for promotion of bswap.
In LegalizeDAG the value is zero-extended to
the new type before byte swapping.  It doesn't
matter how the extension is done since the new
bits are shifted off anyway after the swap, so
extend by any old rubbish bits.  This results
in the final assembler for the testcase being
one line shorter.

8cc364c5cc According to the docs, it is possible to have an
extending load of a vector.  Handle this case when
splitting vector loads.  I'm not completely sure
what is supposed to happen, but I think it means
hi should be set to undef.  LegalizeDAG does not
consider this case.

type is larger than the vector element type.

d164ea2fb0 Ignore TargetConstant with an illegal type. These
are used for passing huge immediates in inline ASM
from the front-end straight down to the ASM writer.
Of course this is a hack, but it is simple, limited
in scope, works in practice, and is what LegalizeDAG
does.

ac6cecec18 It is pointless to turn a UINT_TO_FP into an
SINT_TO_FP libcall plus additional operations:
it might as well be a direct UINT_TO_FP libcall.
So only turn it into an SINT_TO_FP if the target
has special handling for SINT_TO_FP.

b9c33c3229 Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. This
makes their special-case checks of use_size() less beneficial,
so remove them. This eliminates all but one use of use_size(),
which is in AssignTopologicalOrder, which uses it only once for
each node, and so can reasonably afford to recompute it, as
this allows the UsesSize field of SDNode to be removed
altogether.

492f276cbc Move the IsVolatile and SVOffset fields into the MemSDNode base
class, and store IsVolatile and Alignment in a more compact form.
This makes AtomicSDNode slightly larger, but it shrinks LoadSDNode
and StoreSDNode, which are much more common and are the largest of
the SDNode subclasses. Also, this lets the isVolatile() and
getAlignment() accessors be non-virtual.
