This adds support for header deprecation using `LLVM_ATTRIBUTE_C_DEPRECATED` (note that we can't use `LLVM_ATTRIBUTE_DEPRECATED`, which is C++ specific). This will not help people using the FFI interface, but may help people using the C headers.

While migrating the test code away from deprecated APIs I had to add a `LLVMGetGEPSourceElementType()` function, as the necessary functionality didn't seem to be present yet.
