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.

fe0827eed0 [libgomp, nvptx] Fix libgomp.c/target-5.c compilation 
Libgomp test-case libgomp.c/target-5.c is failing to compile when building for
x86_64 with nvptx accelerator due to missing:
- getpid
- gethostname
- isatty (pulled in by fwrite)
in the nvptx newlib.

This patch fixes the build failure by:
- adding a function gomp_print_string which limits the use of fwrite to a single
  location (in affinity-fmt.c), and
- creating an nvptx version of affinity-fmt.c, which:
  - overrides the configure test results HAVE_GETPID and HAVE_GETHOSTNAME, and
  - implements fwrite using write.

Build and reg-tested on x86_64 with nvptx accelerator.

2018-12-13  Tom de Vries  <tdevries@suse.de>

	* affinity-fmt.c (gomp_print_string): New function, factored out of ...
	(omp_display_affinity, gomp_display_affinity_thread): ... here, and ...
	* fortran.c (omp_display_affinity_): ... here.
	* libgomp.h (gomp_print_string): Declare.
	* config/nvptx/affinity-fmt.c: New file.  Include affinity-fmt.c,
	undefining HAVE_GETPID and HAVE_GETHOSTNAME, and mapping fwrite to
	write.
