* The llvm-ints subcommand hasn't been useful for a while since we're just using
hardcoded data layout strings based on the target, rather than the old
approach of building them up piecemeal. We additionally have the
tools/generate_c_size_and_align_checks.zig script for catching C ABI
mismatches. So this libLLVM dependency is not justified anymore.
* The detect-cpu subcommand was at least somewhat useful to compare CPU
detection results between Zig and LLVM. However, its usefulness hinged on
running it natively on every relevant CPU, which we were not actually doing
anyway. Besides, I make a point of porting CPU detection changes in LLVM to
our CPU detection code on every LLVM upgrade - and in some cases, we even do
it more correctly than LLVM now. So the libLLVM dependency brought by this
subcommand also isn't really justified anymore.
