[PATCH] D115283: [AMDGPU] Set "amdgpu_hostcall" module flag if an AMDGPU function has calls to device lib functions that use hostcalls.

If we only need to check whether `__ockl_hostcall_internal` exists in the final module in LLVM codegen to determine whether we need the hostcall metadata, probably we don't even need a function attribute or even module flag.
