https://cygwin.com/pipermail/cygwin/2024-February/255397.html reports a crash on ARM64 probably related to checking x86_64 code on the x86_64 emulator on AArch64.

At least for testing, pull the code checking the host HW up to be called before trying to evaluate assembler code.

This fixes git-for-windows/git#4808

This addresses git-for-windows/git#5239
