[LLVM-C] Add DIBuilder Bindings For Variable Creation

Summary: Wrap LLVMDIBuilderCreateAutoVariable, LLVMDIBuilderCreateParameterVariable, LLVMDIBuilderCreateExpression, and move and correct LLVMDIBuilderInsertDeclareBefore and LLVMDIBuilderInsertDeclareAtEnd from the Go bindings to the C bindings.
