The block address machine operands can reference IR blocks in other functions.
This commit fixes a bug where the references to unnamed IR blocks in other
functions weren't serialized correctly.

This commit implements the initial serialization of the machine operand target
flags. It extends the 'TargetInstrInfo' class to add two new methods that help
to provide text based serialization for the target flags.
This commit can serialize only the X86 target flags, and the target flags for
the other targets will be serialized in the follow-up commits.

This commit removes an outdated TODO comment and a corresponding assertion
which asserts that the mir printer can't the print machine basic blocks that
aren't sequentially numbered.
This comment and assertion were correct when I was working on the patch which
serialized the machine basic blocks, but then I decided to add an 'ID'
attribute to the machine basic block's YAML mapping based on the patch review.
This comment and assertion then became invalid as with the 'ID' attribute we
can serialize the non sequential machine basic blocks and their references
without any problems.

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.

This commit serializes the callee saved information from the class
'MachineFrameInfo'. This commit extends the YAML mappings for the fixed and
the ordinary stack objects and adds an optional 'callee-saved-register'
attribute. This attribute is used to serialize the callee save information.

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.

The jump table info is serialized using a YAML mapping that contains its kind
and a YAML sequence of jump table entries. A jump table entry is a YAML mapping
that has an ID and an inline YAML sequence of machine basic block references.
The testcase 'CodeGen/MIR/X86/jump-table-info.mir' doesn't have any instructions
because one of them contains a jump table index operand. The jump table index
operands will be serialized in a follow up patch, and the appropriate
instructions will be added to this testcase.

This commit serializes the references to the named LLVM alloca instructions from
the stack objects in the machine frame info. This commit adds a field 'Name' to
the struct 'yaml::MachineStackObject'. This new field is used to store the name
of the alloca instruction when the alloca is present and when it has a name.

it can be used by the conversion methods in MIRPrinter and not just the printing
methods in MIPrinter.

This commit serializes the fixed stack objects, including fixed spill slots.
The fixed stack objects are serialized using a YAML sequence of YAML inline
mappings. Each mapping has the object's ID, type, size, offset, and alignment.
The objects that aren't spill slots also serialize the isImmutable and isAliased
flags.
The fixed stack objects are a part of the machine function's YAML mapping.

This commit implements the initial serialization of stack objects from the
MachineFrameInfo class. It can only serialize the ordinary stack objects
(including ordinary spill slots), but it doesn't serialize variable sized or
fixed stack objects yet.
The stack objects are serialized using a YAML sequence of YAML inline mappings.
Each mapping has the object's ID, type, size, offset and alignment. The stack
objects are a part of machine function's YAML mapping.

This commit serializes the 13 scalar boolean and integer attributes from the
MachineFrameInfo class: IsFrameAddressTaken, IsReturnAddressTaken, HasStackMap,
HasPatchPoint, StackSize, OffsetAdjustment, MaxAlignment, AdjustsStack,
HasCalls, MaxCallFrameSize, HasOpaqueSPAdjustment, HasVAStart, and
HasMustTailInVarArgFunc. These attributes are serialized as part
of the frameInfo YAML mapping, which itself is a part of the machine function's
YAML mapping.

This commit changes the type of the field 'Name' in the struct
'yaml::MachineBasicBlock' from 'std::string' to 'yaml::StringValue'. This change
allows the MIR parser to report errors related to the MBB name with the proper
source locations.

This commit adopts the 'ModuleSlotTracker' class, which was surfaced in r240842,
to print the global address operands. This change ensures that the slot tracker
won't have to be recreated every time a global address operand is printed,
making the MIR printing more efficient.

This commit serializes the implicit flag for the register machine operands. It
introduces two new keywords into the machine instruction syntax: 'implicit' and
'implicit-def'. The 'implicit' keyword is used for the implicit register
operands, and the 'implicit-def' keyword is used for the register operands that
have both the implicit and the define flags set.

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.
