  Log Message:
  -----------
  [ADT] add StringViewExtras llvm::starts_with for std::string_view

std::string_view::starts_with isn't available until C++20. Create
llvm::starts_with for now; we can delete this when LLVM moves to C++20
one day.

To run the newly added unit test:
$ cd llvm/build; ninja ADTTests; cd -
$ ./llvm/build/unittests/ADT/ADTTests --gtest_filter=StringViewExtrasTest.\*
