This function only compiles when DEBUG_BISECT is 1, which is often not
the case. As a result there are two commits [1] [2] that break it but
the breakages went unnoticed because the code did not compile by
default. Update the function and include the new header file to make this
function build again.
In order to stop this from happening again, the function is now
compiled unconditionally but exits early unless DEBUG_BISECT is
non-zero. A smart compiler generates no extra code (not even a
function call). But even if it does not, this function does not seem
to be in a hot path that the extra cost becomes a big problem.
