[BOLT] Accept function start as valid jump table entry
Jump tables may contain a function start address. One real-world example
is when a target basic block contains a recursive tail call that is
later optimized/folded into a jump table target.
While analyzing a jump table, we treat start address similar to an
address past the end of the containing function (a result of
__builtin_unreachable), i.e. we require another "regular" entry for the
heuristic to proceed.
