* cpu.c, cpu_asm.S, rtems/score/arm.h, rtems/score/cpu.h,
rtems/score/cpu_asm.h, rtems/score/types.h: ARM port works
well enough to run all sptests, tmtests, and ttcp.
In addition to general cleanup, there has been considerable
optimization to interrupt disable/enable, endian swapping,
and context switching.
