arc: Update legitimate small data address.
All ARC's small data adressing is using address scaling feature of the
load/store instructions (i.e., the address is made of a general
pointer plus a shifted offset. The shift amount depends on the
addressing mode). This patch is checking the offset of an address if
it fits the scalled constraint. If so, a small data access is
generated. This patch fixes execute' pr93249 failure.
