tests/A64: Update {S,U}SHL tests

Browse source 
Converted tests to use oaknut, and added some extra test cases. SSHL's
additional tests are targetd to make sure that the sign of the lowest
byte is used to determine shift direction, not the entire element. USHL
targets this as well as just having more negative (right shift) cases in
general.
