Re: change "microcode: Use fallthrough attribute on clang 10 and 11 too." broke the build for me

[Chris Hanson]

  The problem appears to be between clang 11 and 12. In v11, the attribute isn't recognized, and in v12 it is. 
  
 
  
 Changing the conditional to __clang_major__ >= 12 fixes the problem on macos. 
  
 
  
 Taylor, why did you choose 10 instead?

Does the attached patch work?  Happy to commit if you verify.

Alas, it doesn't.  Transcript attached.

It works fine on Linux, though, for what it's worth.

Also, I managed to submit my other fix from my Linux machine.
