Chris Lattner 125991a1f6 Fix this buggy transformation. Two observations: ...

1. we already know the value is dead, so don't bother replacing 
   it with undef.
2. The very case the comment describes actually makes the load
   live which asserts in deletenode.  If we do the replacement
   and the node becomes live, just treat it as new.  This fixes
   a failure on X86/2008-01-16-InvalidDAGCombineXform.ll with
   some local changes in my tree.

Target

Let each target decide byval alignment. For X86, it's 4-byte unless the aggregare contains SSE vector(s). For x86-64, it's max of 8 or alignment of the type.
