[PATCH] MIR Serialization: Serialize MBB Successors.

[Alex Lorenz]

Hi dexonsmith, bob.wilson, bogner,

This patch is based on a patch that serializes MBB machine operands (http://reviews.llvm.org/D10608).

This patch serializes the machine basic block successors. It uses a YAML flow sequence that contains
strings that have the MBB references. The MBB reference strings use the same syntax as MBB machine
operands in the machine instruction strings.

Example:

  body:
    - id:          0
      name:    entry
      successors:  [ '%bb.1.less', '%bb.2.exit' ]
    - id:          1
      name:    less
    - id:          2
      name:    exit
