You can pass plugins to LDC, which operate on the LLVM IR. There 
is for example a fuzzing plugin that works for Clang and for LDC.

A very simple example can be found in LDC's testsuite: 
https://github.com/ldc-developers/ldc/tree/master/tests/plugins/addFuncEntryCall
This example inserts a function call to "__test_funcentrycall()" 
at the start of every function.

The fuzz plugin is here:
