This patch adds the -fpass-plugin option to flang which dynamically loads LLVM passes from the shared object passed as the argument to the flag.

Features:

- Multiple instances of -fpass-plugin=path-to-file can be specified and each of the files will be loaded in that order.

- The flag can be passed to both flang-new and flang-new -fc1.

- The flag will be listed when the -help flag is passed to both flang-new and flang-new -fc1. It will also be listed when the --help-hidden flag is passed.

- A simple LLVM pass has been included to test this functionality.
