LLVM flang now officially supports PRIF, so that's most likely
what an end user actually wants. Update the install script defaults
to prefer flang, and prompt to brew install it when missing.
Also:
* Demote $CXX to be optional, because C++ is an optional dependency.
* Add invocation of `brew update` may be required to see the latest llvm/flang
* Fix many instances of `${VAR+x}` to `${VAR:+x}`, as the latter also
correctly handles set to an empty string.
* Remove the unnecessary brew tap of fortran-lang/hombrew-fortran,
the fpm cask is now available in the default repository.
…nstalled flang.

This PR converts install.sh so that instead of defaulting to the GCC compiler suite, the install script instead prefers the LLVM compiler suite (both in defaulting the choice of compilers and offering to install compilers via Homebrew).
Fixes #228 (by automating the workaround in install.sh)
Adds macOS CI coverage of install.sh invocation of Homebrew (which was previously missing) and updates documentation.
