This patch renames `flang-new` as `flang`. Similarly to Clang, Flang's
driver executable will be called:
* `flang-<MAJOR_VERSION>`
A symlink called `flang` pointing at `flang-<MAJOR_VERSION>` will be
created at build time. This is consistent with Clang.
For backwards compatibility, a symlink `flang-new` pointing to
`flang-<MAJOR_VERSION>` is also created. This will be removed in the
future.
