[PATCH] Add counter histogram to fdo summary (issue6465057)

[Teresa Johnson]

Sorry about that. I am right now trying to reproduce the
profiledbootstrap problem that H.J. reported, which is on
x86_64-unknown-linux-gnu where I had successfully done a
profiledbootstrap before my commit.

Unfortunately after svn updating my client I am hitting an unrelated
build problem with my profiledbootstrap (it can't find the rule to
make libc++11convenience.la) which is slowing me down.

I don't have access to a gentoo system so I might need your help to
track down the error you reported if it doesn't turn out to be the
same as the one H.J. hit. If you have a bad .gcda file that you could
send me I can start with that. Sounds like there is a profile merging
problem that I didn't see, that is corrupting the gcda files in both
cases.

Thanks,
Teresa
