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. Exon Smith, Matthias Braun, Philip Reames Differential Revision: http://reviews.llvm.org/D9616 llvm-svn: 237708
