The kernel and kext environments do not provide the `__cxa_atexit()` function, so we can't use it for lowering global module destructors. Unfortunately, just querying for "compiling for kernel/kext?" in the LTO pipeline isn't possible (kernel/kext identifier isn't part of the triple yet) so we need to pass down a CodeGen flag. rdar://93536111 Differential Revision: https://reviews.llvm.org/D148967
