We are seeing clang crashes after this patch was relanded in https://reviews.llvm.org/rG73a196a11c0e6fe7bbf33055cc2c96ce3c61ff0d by @jaykang10 . Failed build task: https://ci.chromium.org/ui/p/fuchsia/builders/ci/clang_toolchain.ci.core.arm64-release-subbuild/b8834828820366166433/overview and reproducer: https://storage.cloud.google.com/fuchsia-build/builds/8834828820366166433/bcm-990d09.tar.gz Looks like an assertion error.

I locally revert your change and retest clang with this reproducer and the clang no longer crashes. Could you revert your change if it takes a while to fix it?
