Make EXC_BAD_ACCESS / EXC_I386_GPFLT print nicely in the processor
Currently EXC_BAD_ACCESS doesn't support EXC_I386_GPFLT as exception_flags for pretty-printing in the processor, but this happens for a lot of things: http://opensource.apple.com/source/xnu/xnu-2050.24.15/osfmk/i386/trap.c (search for EXC_I386_GPFLT). And we get a lot of these in the wild: https://crash-stats.mozilla.com/search/?reason=%3DEXC_BAD_ACCESS+%2F+0x0000000d&cpu_name=amd64&_facets=signature&_facets=address&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=address#crash-reports This patch makes them show up with a nice name instead of the current "EXC_BAD_ACCESS / 0x0000000d". Additionally, this patch fixes some other cases where x86-64 wasn't being handled in the same way as x86, and fixes some x86-specific exception flags to be stringified with I386 in the output.
