x86_64: use __cpuid intrinsic
Use the Rust __cpuid and __cpuid_count intrinsics to replace the C implementation in host_cpuid.c. These are defined in core, but they are also re-exported in std, despite being undocumented there due to technical reasons: https://github.com/rust-lang/rust/pull/57808#issuecomment-457390549 Use the std version for consistency (we don't currently use anything from core anywhere else in crosvm). BUG=None TEST=cargo test -p x86_64 TEST=Boot crosvm on x86_64 Change-Id: Ic7a1094d1b804304a2944f8ee1fe55c5e2db23e9 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2067159 Reviewed-by: Zach Reizner <zachr@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Daniel Verkamp <dverkamp@chromium.org>
