The __attribute__((optimize("-O0"))) attribute is used to disable
optimization of some test functions. ARC MWDT toolchain doesn't
support it, however it supports __attribute__((optnone)) with
similar functionality.
Define __no_optimization attribute across all toolchains so it
can be used in tests.
NOTE: we don't define __no_optimization for XCC as it includes
GCC header with __no_optimization defined.
