Khem Raj 5a9c052ba7 amd: Include missing llvm IR header Module.h 
With LLVM-19, Module.h header is not being pulled, which results in
compile errors e.g.

src/amd/llvm/ac_llvm_helper.cpp:102:10: error: no matching function for call to ‘unwrap(LLVMOpaqueModule*&)’
  102 |    unwrap(module)->setTargetTriple(TM->getTargetTriple().getTriple());

                 from ../mesa-24.0.7/src/amd/llvm/ac_llvm_helper.cpp:8:

Its getting the definition from llvm/IR/Type.h instead of Module.h and caused
confusion to compiler

Kai Wasserbäch bc7e363f8e fix: ac/llvm: LLVM 18: remove useless passes, partially removed upstream 
Upstream removed llvm::createLoopSinkPass() in commit
<https://github.com/llvm/llvm-project/commit/b9975cec0ea0a2f10d65b7bd1197d9e1706cbd3d>
and there is no useful alternative except moving to the new pass
manager.

On top of that, the usage of this optimisation pass and
PromoteMemoryToRegisterPass were just useless, according to the
upstream developer of the commit named above. Therefore the easiest
solution is, as him, Marek and Dave suggested, to just remove these two
passes from the pipeline for now.
