This patch add noinline and noclone attributes to naked functions. 
GCC 4.5 has new optimization -fipa-ira which is enabled at -Os and -O2
this option will clone the functions and that can change the standard
calling convention but the naked functions expect that and use
arguments as in standard calling convention. Therefore the naked
functions should not be marked non inline and noclone.
