Support LLVM >=14 #251

Hi, I'm trying to install a library that depends on this package on a device with LLVM version 15.0.7 but I run into this LLVM error:

cabal install haskell-src-exts

Build profile: -w ghc-8.10.7 -O1
In order, the following will be built (use -v for more details):
 - happy-1.20.1.1 (exe:happy) (requires download & build)
 - haskell-src-exts-1.23.1 (lib) (requires download & build)

You are using an unsupported version of LLVM!
Currently only 9 to 14 is supported. System LLVM version: 15.0.7
We will try though...
Cannot specify -O# and --passes=/--foo-pass, use -passes='default<O#>,other-pass'
`opt' failed in phase `LLVM Optimiser'. (Exit code: 1)
cabal: Failed to build exe:happy from happy-1.20.1.1 (which is required by
haskell-src-exts-1.23.1). See the build log above for details.

which seems to imply that newer llvm versions aren't supported.

I'd try a newer GHC, which is more likely to support recent LLVM versions.
