[ARM] Adds test for immediate encoding

Browse Source 
The encoding of expressions as immediates wasn't correct, and was reported in
PR23000. However, we have done some refactoring on how immediates are handled
and now it seems the problem is fixed. This is a test just to make sure it
won't regress again.
