Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting
version 5.5. In version 6.5, they are remapped onto _v2 versions.
The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it
won't work with a cuda driver with driver api version lower than 6.5.
This patch fixes the problem by testing for the presence of the _v2 versions,
and falling back to the original versions in case of absence of the _v2
versions.

This patch adds handling of functions that may not be present in the cuda
driver.
Such a function can be declared using CUDA_ONE_CALL_MAYBE_NULL in cuda-lib.def,
it can be called with the usual convenience macros, but before calling its
presence needs to be tested using new macro CUDA_CALL_EXISTS.
When using the dlopen interface (PLUGIN_NVPTX_DYNAMIC == 1), we allow
non-present functions by allowing dlsym to return NULL. Otherwise
(PLUGIN_NVPTX_DYNAMIC == 0) we declare the non-present function to be weak.
Build and reg-tested libgomp on x86_64 with nvidia accelerator, with and without
--disable-cuda-driver, in combination with a trigger patch that adds a
non-existing function foo to cuda-lib.def:
...
CUDA_ONE_CALL_MAYBE_NULL (foo)
...
and declares it in plugin-nvptx.c:
...
CUresult foo (void);
...
and then uses it in nvptx_init after the init_cuda_lib call:
...
if (CUDA_CALL_EXISTS (foo))
CUDA_CALL (foo);
...

Using libgomp configure option --with-cuda-driver=<dir> we can indicate what
cuda driver to use to build the libgomp nvptx plugin. Without such an option,
the system cuda driver is used, if available. If not availabe, a dlopen
interface is used instead.
However, when we use --without-cuda-driver (or the equivalent
--with-cuda-driver=no) the system cuda driver is still used if available.

interface.

The nvptx port can't support exceptions using sjlj, because ptx does not
support sjlj. However, default_except_unwind_info still returns UI_SJLJ, even
even if we configure with --disable-sjlj-exceptions, because UI_SJLJ is the
fallback option.
The reason default_except_unwind_info doesn't return UI_DWARF2 is because
DWARF2_UNWIND_INFO is not defined in defaults.h, because
INCOMING_RETURN_ADDR_RTX is not defined, because there's no ptx equivalent.
Testcase libgomp.c++/for-15.C currently doesn't compile unless fno-exceptions
is added because:
- it tries to generate sjlj exception handling code, and
- it tries to generate exception tables using label-addressed .byte sequence.
Ptx doesn't support generating random data at a label, nor being able to
load/write data relative to a label.
This patch fixes the first problem by using UI_TARGET for nvptx.
The second problem is worked around by generating all .byte sequences commented
out. It would be better to have a narrower workaround, and define
TARGET_ASM_BYTE_OP to "error: .byte unsupported " or some such.
This patch does not enable exceptions for nvptx, it merely allows c++ programs
to run correctly if they do no use exception handling.

The purpose of the lib-13.f90 test-case is to test acc_wait_all_async. The
test indeed calls acc_wait_all_async, but then subsequentlys calls
acc_wait_all, so the acc_wait_all_async functionality is not tested.
Furthermore, all acc_async_test calls are placed in a location where they are
not guaranteed to succeed, which explains why there's an xfail for the lower

acc_async_test calls to the correct locations.
