Note that the current MicrodumpProcessor::Process implementation has a bug due to the fact that it creates a local Microdump instance, and then holds onto a pointer to the object returned by microdump.GetMemory() which is destroyed when microdump goes out of scope. This CL fixes the crash by making Microdump outlive MicrodumpProcessor, which is the same pattern that Minidump/MinidumpProcessor uses.
