[ARC] Avoid specific constants to end in limm field.
Avoid constants to end up in the limm field for particular
instructions when compiling for size.

xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com>
* config/arc/arc.md (*add_n): Clean up pattern, update instruction
constraints.
(ashlsi3_insn): Update instruction constraints.
(ashrsi3_insn): Likewise.
(rotrsi3): Likewise.
(add_shift): Likewise.
* config/arc/constraints.md (Csz): New 32 bit constraint. It
avoids placing in the limm field small constants which, otherwise,
could end into a small instruction.
