This commit modifies the interface for the machine instruction parsing
functions by wrapping the parameter 'MBBSlots' in a new structure called
'PerFunctionMIParsingState'. This change is useful as in the future I will be
able to pass new parameters to the machine instruction parser just by modifying
the 'PerFunctionMIParsingState' structure instead of adding a new parameter to
each function.

This commit implements serialization of the machine basic block successors. It
uses a YAML flow sequence that contains strings that have the MBB references.
The MBB references in those strings use the same syntax as the MBB machine
operands in the machine instruction strings.

This commit refactors the interface for machine instruction parser. It adopts
the pattern of returning a bool and passing in the result in the first argument
that is used by the other parsing methods for the the method 'parse' and the
function 'parseMachineInstr'.

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 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.
