[PATCH 1/2] [ARC] Fix and refurbish the interrupts.

[claziss@gmail.com]

Hi Jeff,

Please find attached the updated patch.

What is new:
- mailing list feedback is taken into account.
- some comments are updated.
- a new test is added.
- the ARC AUX registers used by ZOL (hardware loop) and FPX (a custom
floating point implementation) are saved before fp-register.
- the millicode optimization is not used by ISR.


Thank you,
Claudiu
