ARC: Use new definitions for optional ARC CPU features
GCC for ARC has been updated to provide consistent naming of preprocessor
definitions for different optional architecture features:
* __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for
-mbarrel-shifter
* __ARC_LL64__ instead of __LL64__ for -mll64
* __ARCEM__ instead of __EM__ for -mcpu=arcem
* __ARCHS__ instead of __HS__ for -mcpu=archs
* etc (not used in newlib)
This patch updates assembly routines for ARC to use new definitions instead
of a deprecated ones. To ensure compatibility with older compiler new
definitions are also defined in asm.h if needed, based on deprecated
preprocessor definitions.
