[PATCH] Fix PR63422 to handle profile insanities

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
