Daniel Grunwald	539e3a906d	Fix #1552 : user-defined and decimal increments For user-defined increments, there were problems with Roslyn was optimizing out one of the stores. The new transform FixRemainingIncrements now takes increments/decrements that were not detected by TransformAssignment and introduces a temporary variable that can be incremented. This sometimes requires un-inlining via the new ILInstruction.Extract() operation. Extract() is not supported in all possible contexts, so it is possible but unlikely that some op_Increment calls remain. For decimals, the situation is different: legacy csc actually was optimizing "d + 1m" to "op_Increment(d)", so we can get rid of any left-over increments by undoing this optimization.

Fix #1552 : user-defined and decimal increments

For user-defined increments, there were problems with Roslyn was optimizing out one of the stores.
The new transform FixRemainingIncrements now takes increments/decrements that were not detected by TransformAssignment and introduces a temporary variable that can be incremented.
