Currently, clang does not emit the `mustprogress` loop or function
attribute for loops with non-zero constant conditionals. Based on recent
discussion in D86844 <https://reviews.llvm.org/D86844> and D86841 <https://reviews.llvm.org/D86841>, it seems that it would be preferable to
emit these attributes to adhere more tightly to the C++ standard as gcc
does.

I will be pushing a patch to add `-ffinite-loops` and `-fno-finite-loops` to
clang to provide more control over this momentarily.
