Rollup merge of #65720 - icefoxen:LLVMgetInstructionCount, r=rkruppe
Add FFI bindings for LLVM's Module::getInstructionCount() Just to make it usable for profiling and such inside rustc itself. It was vaguely useful in https://wiki.alopex.li/WhereRustcSpendsItsTime and I figured I might as well upstream it; I may or may not ever get around to doing more with it (hopefully I will), but it may be useful for others.
