This is an unfinished draft up for discussion.
Moving the discussion of this issue that started in
https://reviews.llvm.org/D113155 to here for clarity.
1. The 'default' switch case falls through to ArchSpec::Core_arm_arm64 due to
the missing 'break', which seems wrong..
2. The following test is failing after #1 is corrected. Additionally, @clayborg
discovered mismatch in cputype between qHostInfo and qProcessInfo.
However, even then the test appears to be failing. GetCompatibleArchs() in
PlatformDarwin.cpp receives ArchSpec::kCore_invalid
Tested on M1 <https://reviews.llvm.org/M1> hardware running MacOS 12.5
