- Changed plug in ArrayImpl taking 'this' as pointer with the ObjectPointerAccess attribute (this solves the foreach test in HashTable)
- Corrected Thread plug signature
- Corrected SpinWait plug signature
- Added plug for Decimal.Equal (strangely was not required before)
There are issue however:
1. IL2CPU modifications are needed (see the PR for the list of the PR of IL2CPU to merge to make this usable)
2. Some fix in IL2CPU seems to give problems with Dictionary (VMT problem again?)
3. Hashtable with valuetype as key doesn't work (ContainsKey() always return false)
