Merging r167855 into 3.2 relase branch
Do not consider a machine instruction that uses and defines the same
physical register as candidate for common subexpression elimination
in MachineCSE.
This fixes a bug on PowerPC in MultiSource/Applications/oggenc/oggenc
caused by MachineCSE invalidly merging two separate DYNALLOC insns.
