panic: Distinguish exceptions from other panics
...
On exceptions and panics, the code will reach panic_rewind. That
function will, among the other things it needs to do to dump the info,
will also dump the exception cause (exccause register). This means that
normally coredumps from panics and those from exceptions are
indistinguishable.
In this commit I reserve the maximum value for exccause (63) to signify
that the dump actually came from a panic instead of a hardware
exception. The easiest way I could see that would not duplicate code is
to simply set the exccause register to this reserved value (otherwise it
could be undefined, as it's not initialized at boot).
I also update the core dumper tool to use 63 as the value reserved for
panics instead of 0 (which is IllegalInstructionCause, a valid hardware
exception).
