1. Reverted these two commits which restore switch statement.

2. Adjusted the pseudocode so that it avoids the overflow (sm is 2-bit, adding
1 to sm=0x3 wil yield sm=0x0).

3. Supported the concatenation for variables deep inside selectable integers
(logically this should've been the first).

4. Provided the tests for shadd/shadduw.
