[cfe-dev] [analyzer] The use of tblgen in the analyzer

I have two questions about this topic.
1. Checker registration:
I am in the process of updating clang-analyzer.llvm.org, and as I went
through the checkers that were missing, I encountered this:
def NonnullGlobalConstantsChecker: Checker<"NonnilStringConstants">,
HelpText<"Assume that const string-like globals are non-null">,
What is particularly interesting here (other than the mismatched names), is
that NonilStringConstantsChecker.cpp doesn't exist, in fact it never did.
To my greatest surprise, DescFile isn't used anywhere!
#define CHECKER(FULLNAME,CLASS,DESCFILE,HELPTEXT,GROUPINDEX,HIDDEN) \
registry.addChecker(register##CLASS, FULLNAME, HELPTEXT);
So, is there a point in keeping DescFile entries?
2. Use tblgen for AnalyzerOptions:
I dislike that I need to look at source code, or doxygen at best to know
what kind -analyzer-config options are available. Would it be a good idea
for me to refactor it with tblgen?
