MIR Serialization: Serialize the unnamed basic block references.

Browse Source 
This commit serializes the references from the machine basic blocks to the
unnamed basic blocks.

This commit adds a new attribute to the machine basic block's YAML mapping
called 'ir-block'. This attribute contains the actual reference to the
basic block.

Reviewers: Duncan P. N. Exon Smith
