Unfortunately, there is no codegen path for this (for the moment).

This patch is related to the work I started in https://reviews.llvm.org/D139024, which forces the emission of CFI entries in the `.eh_frame` section for functions with the `uwtable` attribute.

The problem is that without this patch https://reviews.llvm.org/D139024 breaks the compilation of AMDGPU programs when the sanitizers are enabled (`lld` raises an error due to the problematic relocations).

With the work from https://reviews.llvm.org/D139024 , this case will be triggered for functions with the `uwtable` attribute.
