Tobias Burnus 683f118439 OpenMP: Move omp requires checks to libgomp 
Handle reverse_offload, unified_address, and unified_shared_memory
requirements in libgomp by saving them alongside the offload table.
When the device lto1 runs, it extracts the data for mkoffload. The
latter than passes the value on to GOMP_offload_register_ver.

lto1 (either the host one, with -flto [+ ENABLE_OFFLOADING], or in the
offload-device lto1) also does the the consistency check is done,
erroring out when the 'omp requires' clause use is inconsistent.

For all in-principle supported devices, if a requirement cannot be fulfilled,
the device is excluded from the (supported) devices list. Currently, none of
those requirements are marked as supported for any of the non-host devices.

Kwok Cheung Yeung b52643ab90 libgomp: Fix hang when profiling OpenACC programs with CUDA 9.0 nvprof 
The version of nvprof in CUDA 9.0 causes a hang when used to profile an
OpenACC program.  This is because it calls acc_get_device_type from
a callback called during device initialization, which then attempts
to acquire acc_device_lock while it is already taken, resulting in
deadlock.  This works around the issue by returning acc_device_none
from acc_get_device_type without attempting to acquire the lock when
initialization has not completed yet.

Maciej W. Rozycki 6c84c8bf9b Add OpenACC 2.6 `acc_get_property' support 
Add generic support for the OpenACC 2.6 `acc_get_property' and
`acc_get_property_string' routines, as well as full handlers for the
host and the NVPTX offload targets and minimal handlers for the HSA,
Intel MIC, and AMD GCN offload targets.

Included are C/C++ and Fortran tests that, in particular, print
the property values for acc_property_vendor, acc_property_memory,
acc_property_free_memory, acc_property_name, and acc_property_driver.
The output looks as follows:

Vendor: GNU
Name: GOMP
Total memory: 0
Free memory: 0
Driver: 1.0

with the host driver (where the memory related properties are not
supported for the host device and yield 0, conforming to the standard)
and output like:

Vendor: Nvidia
Total memory: 12651462656
Free memory: 12202737664
Name: TITAN V
Driver: CUDA Driver 9.1

with the NVPTX driver.
