This suggestion doesn't make sense to me. The order of events:

1. https://reviews.llvm.org/rG3cc3c0f8352ec33ca2f2636f94cb1d85fc57ac16 landed, 
broke the build
2. 1 was reverted in 
https://reviews.llvm.org/rGbf2479c347c8ca88fefdb144d8bae0a7a4231e2a
3. 1 was relanded in 
https://reviews.llvm.org/rG76d9bc72784d88f4dd57b9939e52c73739438af5
4. different patch was landed 
https://reviews.llvm.org/rGfd11a26d368c5a909fb88548fef2cee7a6c2c931
5. @thakis  reports patch from 4 causes a test failure, but the test failure 
looks like the test failure from 1, not 4.
6. 4 is reverted in 
https://reviews.llvm.org/rG9145a3d4ab7eb05d9fb113b5392e8961df629b88

#5 doesn't make sense to me, and I don't see how the test would turn out 
differently on an m1 mac vs x86
