https://reviews.llvm.org/D158247 caused regressions for HIP on Windows and was reverted. A reduced test case is: ``` typedef void (__stdcall* funcTy)(); void invoke(funcTy f); static void __stdcall callee() noexcept { } void foo() { invoke(callee); } ``` It is due to clang missing handling host/device attributes for calling convention at a few places This patch fixes that.
