This was tracked as PR91.
	* rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which
	is used to specify if the port uses the standard macro for this (FALSE).
	A TRUE setting indicates the port provides its own implementation.
	* rtems/score/c_isr.inl: Deleted and contents merged into cpu.c.
	* cpu.c: Received contents of c_isr.inl.
	* Makefile.am: Deleted reference to c_isr.inl.
