The new LLVM stack save/restore intrinsic operations are more convenient than function calls because they do not add function declarations to the module and therefore do not block the parallelisation of passes. Furthermore they could be much more easily marked with memory effects than function calls if that ever proved useful. This builds on top of #107879. Resolves #108016
