build: update llvm tag to 7ccbb4df (#1736)
Summary of changes:

 - LLVM now includes <optional> instead of "llvm/ADT/Optional.h" in most
   (although not all) places
   (https://reviews.llvm.org/rG541ef3d61e9341cd38420c0dbca9250c4d0ea04c).
   This patch replaces the affected instances of `llvm::Optional` with
   `std::optional`.

 - In the usages of llvm::Optional that remain, llvm::Optional::value()
   is deprecated, so this patch replaces them with a dereference.
