Subject: [PATCH v14 4/4] meson: Add LLVM bitcode emissions for contrib
 libraries

The libraries for which bitcode files are generated are selected
manually. Bitcode is only worthwhile for extensions that provide
lightweight SQL operators/functions that can benefit from being inlined
into JIT-compiled expressions, so this is restricted to citext, hstore,
intarray, ltree and pg_trgm.
