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. Reviewers: Duncan P. N. Exon Smith Differential Revision: http://reviews.llvm.org/D10481 llvm-svn: 240295
