Dispose llvm::TargetMachines prior to llvm::Context being disposed
If the TargetMachine is disposed after the Context is disposed, it can lead to use after frees in some cases. I've observed this happening occasionally on code compiled for aarch64-pc-windows-msvc using `-Zstack-protector=strong` but other users have reported AVs from host aarch64-pc-windows-msvc compilers as well.
