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. Reviewers: Duncan P. N.
