Properly update symbol dependencies when updating a cached module

[ryuukk]

Solves this particulate case

module a;

import b;

b.data // if we edit the module C, then the modulecache doesn't properly propagate the changes to module c and its dependents because of the ownership check

module b;
import c;
StructFromC data;

module c;

struct StructFromC
{}

Additionally the complexity is increased by this as you linearly go through the range instead of having an optimized tree search to find equal parts.

The opSlice seems to be a difference that could affect how this loop works, but that sounds to me rather that either the API usage to call .parts here is wrong or that the iterator has some bug that should be fixed.

Also this is missing a test showing how it was broken before but now working.

this part seems useless, the part == newPart above should call DSymbol.opEquals which is implemented by part.name == newPart.name, so this if should never actually match

[ryuukk]

the part == newPart only check the pointer, not the value?

as for the test, i have no clue what to do lol, if the current tests pass, i guess it should be fine

What's the status on this?
