This commit serializes the offset for the following operands: target index,
global address, external symbol, constant pool index, and block address.
llvm-svn: 244157
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.
