  Log Message:
  -----------
   This patch extends the OptimizeGlobalAddressOfMalloc to handle the null check of global pointer variables. It is disabled with https://reviews.llvm.org/rGb7cd291c1542aee12c9e9fde6c411314a163a8ea. This PR is to reenable it while fixing the original problem reported. The fix is to set the store value correctly when creating store for the new created global init bool symbol.
