[llvm-dev] New TableGen backend for debugging

I'm glad you find it useful. I haven't thought about it being done as part of the build, nor am I any sort of build guru. What do other people think?

It prints all the global variables, classes, and records with more detail than the default backend. In particular, it includes the source locations of the class and record definitions, and the source locations of the places where field values were set. It also includes the defm sequence for records that were generated by one or more defm statements.
