Alex Lorenz 78d7831b0f MIR Serialization: print and parse machine function names.
This commit introduces a serializable structure called
'llvm::yaml::MachineFunction' that stores the machine
function's name. This structure will mirror the machine 
function's state in the future.

This commit prints machine functions as YAML documents
containing a YAML mapping that stores the state of a machine
function. This commit also parses the YAML documents
that contain the machine functions.

Alex Lorenz 2bdb4e1063 Resubmit r237954 (MIR Serialization: print and parse LLVM IR using MIR format).
This commit a 3rd attempt at comitting the initial MIR serialization patch.
The first commit (r237708) was reverted in 237730. Then the second commit
(r237954) was reverted in r238007, as the MIR library under CodeGen caused
a circular dependency where the CodeGen library depended on MIR and MIR
library depended on CodeGen.

This commit has fixed the dependencies between CodeGen and MIR by
reorganizing the MIR serialization code - the code that prints out
MIR has been moved to CodeGen, and the MIR library has been renamed
to MIRParser. Now the CodeGen library doesn't depend on the
MIRParser library, thus the circular dependency no longer exists.

--Original Commit Message--

MIR Serialization: print and parse LLVM IR using MIR format.

This commit is the initial commit for the MIR serialization project.
It creates a new library under CodeGen called 'MIR'. This new
library adds a new machine function pass that prints out the LLVM IR
using the MIR format. This pass is then added as a last pass when a
'stop-after' option is used in llc. The new library adds the initial
functionality for parsing of MIR files as well. This commit also
extends the llc tool so that it can recognize and parse MIR input files.
