Jinsong Ji 9577086628 [MachinePipeliner] Fix order for nodes with Anti dependence in same cycle 
Summary:
Problem exposed in PowerPC functional testing.

We did not consider Anti dependence for nodes in same cycle,
so we may end up generating bad machine code.
eg: the reduced test won't verify.

*** Bad machine code: Using an undefined physical register ***
- function:    lame_encode_buffer_interleaved
- basic block: %bb.4  (0x4bde4e12928)
- instruction: %29:gprc = ADDZE %27:gprc, implicit-def dead $carry, implicit $carry
- operand 3:   implicit $carry
