[LLVM-C] Add LLVMGetHostCPU{Name,Features}.
Without these functions it's hard to create a TargetMachine for
Orc JIT that creates efficient native code.
It's not sufficient to just expose LLVMGetHostCPUName(), because
for some CPUs there's fewer features actually available than
the CPU name indicates (e.g. AVX might be missing on some CPUs
identified as Skylake).
