IMPALA-6824: Fix crash in RuntimeProfile::EventSequence::AddNewerEvents()

When events_ is empty in runtime-profile-counters.h:347, events_.back()
is undefined. This can lead to a crash. The fix is to check for
events_.empty() before calling back().

Patch Set 1:

You mentioned that status updates come in before any local events were logged, which caused this crash. That should be a case that we support right?

Why can't we add a backend test for this that does exactly that? Have a 'RuntimeProfile' with no events and then call update on it with a 'TRuntimeProfileNode' that has an 'EventSequence'.

Hello Sailesh Mukil, Tim Armstrong, Csaba Ringhofer, 

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/9951

to look at the new patch set (#2).

Change subject: IMPALA-6824: Fix crash in RuntimeProfile::EventSequence::AddNewerEvents()
......................................................................

IMPALA-6824: Fix crash in RuntimeProfile::EventSequence::AddNewerEvents()

When events_ is empty in runtime-profile-counters.h:347, events_.back()
is undefined. This can lead to a crash. The fix is to check for
events_.empty() before calling back().

This change adds a backend test to make sure that updating empty event
sequences doesn't crash.

Hit IMPALA-6338. This test was actually disabled today afternoon because it is a known flaky. I will rebase this change now and try again.

Let's not bother reserving, this code isn't perf critical so it doesn't really matter if there's an extra malloc() call or two - doesn't seem worth the complication.

This will over reserve, if there are timestamps <= last_timestamp. As 'timestamps' is sorted, a for loop could count till the first element to append, reserve the exact size, and the next for loop could simply push_back the rest.
