Build script for Flang-f18 (flang-new) + LLVM

This is a Bash script (macOS, Linux, ...) for building Flang-f18 and LLVM from source. It is adapted from Jeff Hammond

Ninja: recommended for best build efficiency and speed.

In general, a recent GCC would work. On macOS, system AppleClang compiler can be used as well.
