  ARC has enter_s/leave_s instructions which can save/restore the entire
function context. It is not needed the millicode thunks anylonger when
compiling for size, thus, make their usage optional.

gcc/

	* common/config/arc/arc-common.cc (arc_option_optimization_table):
	Remove millicode from list.

gcc/testsuite/

	* gcc.target/arc/milli-1.c: Update test.
