Martin Åberg 83f733ce59 SPARC: improve fatal log
The fatal log now contains
- Trap type in human readable representation
- Integer registers visible to the program when trap was taken
- Special register values such as PC and PSR
- Backtrace with PC and SP

If CONFIG_EXTRA_EXCEPTION_INFO is enabled, then all the above is
logged. If not, only the special registers are logged.

The format is inspired by the GRMON debug monitor and TSIM simulator.
A quick guide on how to use the values is in fatal.c.

It now looks like this:

E: tt = 0x02, illegal_instruction
E:
E:       INS        LOCALS     OUTS       GLOBALS
E:   0:  00000000   f3900fc0   40007c50   00000000
