llvm: backport "[SimplifyCFG] Hoisting invalidates metadata". Fixes #36023 by backporting @majnemer's LLVM patch fixing [the LLVM bug](https://llvm.org/bugs/show_bug.cgi?id=29163.) where SimplifyCFG hoisted instructions andkept their metadata (conditional `!nonnull` loads could kill a null check later if hoisted). r? @alexcrichton |

This directory currently contains some LLVM support code. This will generally be sent upstream to LLVM in time; for now it lives here. NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never* be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here. Functions that return a failure status and leave the error in the LLVM last error should return an LLVMRustResult rather than an int or anything to avoid confusion. When translating enums, add a single `Other` variant as the first one to allow for new variants to be added. It should abort when used as an input. All other types must not be typedef-ed as such.
