Most GNU and LLVM-based compilers allow using the
--mcpu nativeflag to tune the performance for the host cpu.This patch adds support for passing this flag. It will get turned into the host CPU name.
For this, a LLVM#host_cpu_name method was added (because I didn't find a better place).
There are currently no specs as a test case would depend on the architecture of the machine running the specs.
This is my first contribution so feel free to notice me if there's something to improve.
