Backport trunk r223801:

    gcc/
    * builtins.c (expand_builtin_acc_on_device): Don't use open-coded
    sequence for !ACCEL_COMPILER.

    libgomp/
    * oacc-init.c (plugin/plugin-host.h): Include.
    (acc_on_device): Check whether we're in an offloaded region for
    host_nonshm
    plugin. Don't use __builtin_acc_on_device.
    * plugin/plugin-host.c (GOMP_OFFLOAD_openacc_parallel): Set
    nonshm_exec flag in thread-local data.
    (GOMP_OFFLOAD_openacc_create_thread_data): Allocate thread-local
    data for host_nonshm plugin.
    (GOMP_OFFLOAD_openacc_destroy_thread_data): Free thread-local data

[PR libgomp/65742, PR middle-end/66332] XFAIL acc_on_device compile-time
evaluation

The OpenACC 2.0a specification mandates differently, but we currently do get a
library call in the host code.

Backport trunk r224028:

        PR libgomp/65742
        PR middle-end/66332

        gcc/testsuite/
        * c-c++-common/goacc/acc_on_device-2.c: XFAIL for C, too.
