[BUG] clang frontend crashes on both r26d and canary version about ndk HOT 5 OPEN

(thank you for the quality bug report, btw, that makes things much easier)

https://r.android.com/3075606 picks the fix into AOSP toolchain. We'll include the fix in r27.

The godbolt repro crashes back to clang 16. This is not a regression, so we will cherry-pick the fix to r27.

Switching godbolt over to the assertions enabled clang shows an assertion failure: https://godbolt.org/z/xh35qaoed

It also fails consistently from clang 16 through HEAD, so not a regression. We might be able to pick up the fix for r27, depending on how invasive it is, but getting the fix into r26e (which isn't currently planned, as there are no regressions against it) seems unlikely.
