Description

We don't support code like this:

someStruct.PointerField += i;
int* x = someStruct.PointerField++;

I'm not sure if it's worth adding support for these constructs -- these are two quite complex features interacting with each other; and such code is quite rare.

Contributor guide

Research direction
Investigate how pointer field access and arithmetic are currently decompiled. Look at existing handling of pointer dereference and binary operations. Add support for compound assignments (+=, =, etc.) and postfix/prefix increment/decrement on pointer fields.
