You need to traverse the IL and examine the LHS and RHS of
expressions for COMPONENT_REF and INDIRECT_REF expressions. In
GIMPLE these expressions may only appear on the LHS or RHS of
assignments, and in function arguments.
You then need to walk the expression looking for FIELD_DECLs.
And you had better do this before SRA (which will decompose most
structure references into compiler generated scalars).
