I've been seeing intermittent failures of AllClangUnitTests/TimeProfilerTest/ConstantEvaluationCxx20 and AllClangUnitTests/TimeProfilerTest/ConstantEvaluationC99 on my MacOS bot, but I haven't had a chance to try and figure out if it might be related to your change or not.

ConstantEvaluationCxx20:
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19393
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19381
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19356
ConstantEvaluationC99:
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19383
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19376
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19366
 - https://lab.llvm.org/buildbot/#/builders/190/builds/19343

First instance of either failing: https://lab.llvm.org/buildbot/#/builders/190/builds/19216
