[ECOS] amount of cpu state to be saved for exceptions

in __default_exception_handler, cyg_hal_exception_handler is passed the address 
of saved CPU state.

since we don't know, in what way application installed handler would want to 
make use of saved state (it might choose to look at some/all of the saved cpu 
state), we can't drop any savings even for production kernel, where for speedups 
we could drop saving callee-saved registers in case of interrupts.

Every program is a part of some other program, and rarely fits.
