compiler: better crash handler

Far simpler, because everything which `crash_report.zig` did is now
handled pretty well by `std.debug` anyway. All we want is to print some
context around panics and segfaults. Using the new ability to override
the default segfault handler while still having std handle the
target-specific bits for us, that's really simple.
