[PATCH] D18749: Add LLVMGetAttrKindIDInContext in the C API in order to facilitate migration away from LLVMAttribute

[whitequark via llvm-commits]

whitequark added a comment.

@rafael The C enum doesn't help much since frontends using libffi to bind to the C API have to duplicate the enum in the binding. Whereas, the function will work for at least removed attributes (it can return 0 and signal an error to the frontend).
