MIR Serialization: Initial serialization of machine constant pools.

Browse Source 
This commit implements the initial serialization of machine constant pools and
the constant pool index machine operands. The constant pool is serialized using
a YAML sequence of YAML mappings that represent the constant values.
The target-specific constant pool items aren't serialized by this commit.

Reviewers: Duncan P. N. Exon Smith
