We need to make sure that the parts of the crash info structure that we read 
are compatible between versions 4 and 5. If they are, this is an easy fix. 
Otherwise, we need to figure out what’s changed and how to make sense of it.

a0ed0345245537/snapshot/mac/process_types/crashreporterclient.proctype has 
useful context.

I’ll be installing the 10.11 preview in a VM to run Crashpad’s tests, too.

This was caught by a test. crashpad_snapshot_test 
MachOImageAnnotationsReader.CrashAbort fails in Mac OS X 10.11.
