[Niram7777]

Fix build error, the Triple constructor is not implicit anymore.

[marin@pc-linux ~]$ clang++ --version

The Triple constructors only exist in llvm/llvm-project@fff720d#diff-5008de5706b85963c456532be4d2e8c5b478959be9d315f77c338946bd1fc586R353-R354
We can reopen the PR once we upgrade LLVM

You can also leave it up as draft

Is it possible to use ifdefs in the style of minimum version to build LLVM 19 and LLVM 21?

	auto null_mod = std::make_unique<llvm::Module>("null_", *m_context);
#if LLVM_VERSION_MAJOR > 20
	null_mod->setTargetTriple(llvm::Triple(jit_compiler::triple1()));
#else
	null_mod->setTargetTriple(jit_compiler::triple1());
#endif

This fixes the compilation error for LLVM triple on Windows Msys2 clang64 when wrapping all the explicit Triples.

@qurious-pixel yes

@Niram7777 if you can add the ifdefs, we can merge this

I just found there was #16807 but I have updated my PR in case you want to handle all LLVM versions and a quick fix

With this commit and #17552, Clang should build again.
