Author: Ben Niu <be...@microsoft.com> Date: Thu Jan 21 09:56:17 2021 -0800 util: When building 'ARM64EC', don't use x64 intrinsics which need to be emulated ARM64EC is a new build target for Windows ARM64 devices for x64 support. These binaries can be loaded in x64 processes, but don't need to be emulated. For code that's heavily used, avoiding the emulation can be a huge perf win.
