ARCv2: update memset() so it could be used without double load/stores
Existing version of memset() relies on existence of 64-bit load/stores.
While ARC HS38 may not have those instructions implemented in SoC.
Proposed implementation checks if "-mno-ll64" option was passed to gcc
(for ARCv2 "-mll64" is set implicitly by default) by checking __LL64__
definition and if it is not defined uses 32-bit load/stores.
