This commit serializes the global address machine operands.
This commit doesn't serialize the operand's offset and target
flags, it serializes only the global value reference.

This commit serializes machine basic block operands. The
machine basic block operands use the following syntax:
%bb.<id>[.<name>]
This commit also modifies the YAML representation for the
machine basic blocks - a new, required field 'id' is added
to the MBB YAML mapping.
The id is used to resolve the MBB references to the
actual MBBs. And while the name of the MBB can be
included in a MBB reference, this name isn't used to
resolve MBB references - as it's possible that multiple
MBBs will reference the same BB and thus they will have the
same name. If the name is specified, the parser will verify
that it is equal to the name of the MBB with the specified id.

This commit serializes the 3 scalar boolean attributes from the
MachineRegisterInfo class: IsSSA, TracksRegLiveness, and
TracksSubRegLiveness. These attributes are serialized as part
of the machine function YAML mapping.

This commit serializes the null register machine operands.
It uses the '_' keyword to represent them, but the parser
also allows the '%noreg' named register syntax.

This commit implements initial machine instruction serialization. It
serializes machine instruction names. The instructions are represented
using a YAML sequence of string literals and are a part of machine
basic block YAML mapping.
This commit introduces a class called 'MIParser' which will be used to
parse the machine instructions and operands.

This commit implements the initial serialization of machine basic blocks in a
machine function. Only the simple, scalar MBB attributes are serialized. The
reference to LLVM IR's basic block is preserved when that basic block has a name.

This commit decouples the MIR printer and the MIR printing pass so
that it will be possible to move the MIR printer into a separate
machine IR library later on.
