fd6673cf7f On big-endian machines it is wrong to do a full 
width register load followed by a truncating
store for the copy, since the load will not place
the value in the lower bits.  Probably partial
loads/stores can never happen here, but fix it
anyway.

05e11fab87 When expanding unaligned loads and stores do not make 
use of illegal integer types: instead, use a stack slot
and copying via integer registers.  The existing code
is still used if the bitconvert is to a legal integer
type.

This fires on the PPC testcases 2007-09-08-unaligned.ll
and vec_misaligned.ll.  It looks like equivalent code
is generated with these changes, just permuted, but
it's hard to tell.

With these changes, nothing in LegalizeDAG produces
illegal integer types anymore.  This is a prerequisite
for removing the LegalizeDAG type legalization code.

While there I noticed that the existing code doesn't
handle trunc store of f64 to f32: it turns this into
an i64 store, which represents a 4 byte stack smash.
I added a FIXME about this.  Hopefully someone more
motivated than I am will take care of it.

d350e02e19 - Use patterns instead of creating completely new instruction matching patterns, 
which are identical to the original patterns.

- Change the multiply with overflow so that we distinguish between signed and
  unsigned multiplication. Currently, unsigned multiplication with overflow
  isn't working!

ab55ebda1c Redo the arithmetic with overflow architecture. I was changing the semantics of 
ISD::ADD to emit an implicit EFLAGS. This was horribly broken. Instead, replace
the intrinsic with an ISD::SADDO node. Then custom lower that into an
X86ISD::ADD node with a associated SETCC that checks the correct condition code
(overflow or carry). Then that gets lowered into the correct X86::ADDOvf
instruction.

Similar for SUB and MUL instructions.
