18a8452f3d A bit more memset / memcpy optimization. 
Turns them into calls to memset / memcpy if 1) buffer(s) are not DWORD aligned,
2) size is not known to be greater or equal to some minimum value (currently 128).

2486af1b53 Prevent certain nodes that have already been selected from being folded into 
X86 addressing mode. Currently we do not allow any node whose target node
produces a chain as well as any node that is at the root of the addressing
mode expression tree.
