I would like to query at certain points in unfortunately various files
like SemaExpr.cpp or CGCall.cpp the value of a compiler flag and branch
accordingly to custom code.
The specific flag I want to query the value of is -fobjc-runtime.
I have now spent some time in various corners of clang, certainly not
all, but I haven't come across that yet, except possibly LangOptions.
Maybe extending LangOptions would be the best place, but I don't know.
Thanks for a clue.
