[Icc-430] Interrupt handler wrapper preserves R8,9 - repost

[Richard]

Kris, there is no interrupt wrapper per se. The compiler checks what the 
register usage is for an interrupt function and only save and restore what 
are used. If you have a test case that shows otherwise, then it is a bug. 
So contact me offlist with the source code and I will take a look at it.

If an ISR calls another function, then the compiler will save/restore all 
registers as it wouldn't know what get used in the end, but this doesn't 
sound like your issue.
