@afd afd commented Feb 9, 2020

This change ensures that global and local variables donated from other
modules are always initialized at their declaration in the module
being transformed. This is to help limit issues related to undefined
behaviour that might arise due to accessing uninitialized memory.

The change also introduces some helper functions in fuzzer_util to
make it easier to find the pointee types of pointer types.
