[funcattrs] check reachability to improve noreturn
There was a fixme in the code pertaining to attributing functions as
noreturn. By using reachability, if none of the blocks that are
reachable from the entry return, then the function is noreturn.
Previously, the code only checked if any blocks returned. If they're
unreachable, then they don't matter.
This improves codegen for the Linux kernel.
