Alkis Evlogimenos 6a35516dcc Add back machine code deleter pass until we get a MachineCode pass
that will be responsible for the creation of MachineFunctions and will
be required by all MachineFunctionPass passes.

Alkis Evlogimenos 80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.
