LLVM kaleidoscope example

Notes

1. KaleidoscopeJIT.h copied from llvm 18.1.7 source tree: examples/Kaleidoscope/include/KaleidoscopeJIT.h (I'm attempting to build with 18.1.5, maybe inviting trouble here).
2. Using xo-cmake cmake macros. To install:

   $ cd ~/proj
   $ git clone https://github.com/Rconybea/xo-cmake.git  # creates xo-cmake
   $ cd xo-cmake
   $ PREFIX=/usr/local                                   # ..or desired install location;  want PREFIX/bin in PATH
   $ cmake -DCMAKE_INSTALL_PREFIX=${PREFIX} -B .build -S .
   $ cmake --install -B .build
