[ARC] Improves and fixes for small data support.
Add alignment check for short load/store instructions used for sdata,
as they request 32-bit aligned short immediate. Use sdata symbol
alignment information and emit scalled loads/stores whenever is
possible. The scalled address will extend the access range for sdata
symbols. Allow 64-bit datum into small data section, if double
load/store instructions are present.
