- Altered the InitializerPeepholeTransforms' ArrayInitializer forward-scan to only look at the next instruction: in practice, CSC does not seem to generate code that needs anything more, and there are some questions as to the validity of the looping itself (i.e. what if there is a branch between them?

- Added another test to the InitializerTests, to validate that it handles deeper multi-dimensional arrays (I went 3x3x3 for simplicity)
