It looks like some of these changes are causing compiler to crash in `clang::ASTContext::getFloatTypeSemantics` during CUDA compilation:
https://lab.llvm.org/buildbot/#/builders/55/builds/35047

I'm currently working on narrowing down which commit is the culprit. Here's a snippet of the stack trace:
