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.
