Owen Anderson 452bd5f9c6 Fix an issue with the MergeBasicBlockIntoOnlyPred() helper function where it did ...

not properly handle the case where the predecessor block was the entry block to
the function.  The only in-tree client of this is JumpThreading, which worked
around the issue in its own code.  This patch moves the solution into the helper
so that JumpThreading (and other clients) do not have to replicate the same fix
everywhere.
