d1c4f4c833 Add support for the rep movs[bwd] instructions, and emit them when code 
generating the llvm.memcpy intrinsic.

b755d35fd2 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.

676e5b8997 Modify the two address instruction pass to remove the duplicate 
operand of the instruction and thus simplify the register allocation.

41bd8284e3 Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

ef1bfa35d0 Finally, _actually delete the machine code_ for a function, after it has 
been emitted.  Also, since the FPK pass is causing memory access violations,
disable it.

93c209e4ac Modified cast so that it converts the int to a long before casting to 
a pointer.  This evades a warning emitted by GCC when we cast from
unsigned int (32 bit) to void * (64 bit) on SparcV9.

5a577c0b28 * Rename X86::IMULr16 -> X86::IMULrr16 
* Implement R1 = R2 * C where R1 and R2 are 32 or 16 bits. This avoids an
  extra copy into a register, reducing register pressure.
