Hi ports --

Attached is a new port, lang/flang/f18. F18 is the new LLVM Fortran
compiler.

Some explanation:
Flang isn't going anywhere. It is still a production-quality Fortran
compiler built on top of LLVM (it's basically PGI Fortran bolted on top
of an LLVM IR generator, for those keeping score at home). However,
Flang isn't suitable for being donated directly to the LLVM project,
which was one of the goals of open sourcing the PGI Fortran compiler.

F18 is designed to meet this goal. It is a completely new from the
ground-up Fortran compiler. The conversation about donating F18 to LLVM
began recently, so I think now is the time to get this into ports. It's
written in C++17, so clang-only for now though once ports-gcc moves to
8.2.0 it will build with that too. I've tested with both compilers.

What F18 is not:
* A finished compiler. It will parse and validate your Fortran code but
it will not produce LLVM IR or native code. The Flang team expect F18 to
begin generating LLVM IR in about two to three months time.
* A replacement for Flang. Flang isn't going anywhere.

This port is for people who are looking to get their hands dirty with
the new compiler. The Flang team overall has been really great getting
OpenBSD issues resolved in both Flang and F18; I've had f18 on my
machine since the repo was posted a little over a year ago.

NOTE: F18 requires a lot of memory to build.

Attached is the tarball for the new port and a diff to tweak the flang
scaffolding to include f18.

OK?
