- ``externally_initialized`` variables would be initialized or modified elsewhere. Particularly, CUDA or HIP may have host code to initialize or modify ``externally_initialized`` device variables, which may not be explicitly referenced on the device side but may still be used through the host side interfaces. Not preserving them triggers the elimination of them in the GlobalDCE and breaks the user code. Reviewed By: yaxunl Differential Revision: https://reviews.llvm.org/D105135
