This patch removes some asserts my jump threading patch r215739 added.
An upstream pass (copyrename2) is introducing some bogus profile
counts, so we can't assert that counts are 0 when there is no profile
data for the function.

Tested on testcase attached to PR63422. Currently running gcc
regression tests for x86_64-unknown-linux-gnu. Ok for trunk if that
passes?

Thanks,
Teresa
