This is the beginning of an effort to move the codeview yaml reader / writer into ObjectYAML so that it can be shared. Currently the only consumer / producer of CodeView YAML is llvm-pdbdump, but CodeView can exist outside of PDB files, and indeed is put into object files and passed to the linker to produce PDB files. Furthermore, there are subtle differences in the types of records that show up in object file CodeView vs PDB file CodeView, but they are otherwise 99% the same. By having this code in ObjectYAML, we can have llvm-pdbdump reuse this code, while teaching obj2yaml and yaml2obj to use this syntax for dealing with object files that can contain CodeView. This patch only adds support for CodeView type information to ObjectYAML. Subsequent patches will add support for CodeView symbol information. llvm-svn: 304248
