Removal of HSA offloading from gcc and libgomp

This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.

Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place.  I did
not remove everything these patches brought in, for example:

  - the mechanism to pass offload-target specific info from the application to
    the offloading plugin - but the same mechanism is also used to
    communicate number of teams and the thread limit to all offload targets.

  - run_func hook in gomp_device_descr stays too, although now it is
    not used.  If some future offload target would like the ability to
    refuse to offload some functions, it can use it.  It is easy to
    remove as a follow-up if it is considered clutter, though.

  - configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
    and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.

  - Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
    from gomp-constants.h) appears in the source of the amdgcn libgomp
    plugin, although I tend to think that code path is not ever used
    and this patch certainly removes it from the compiler.
    Nevertheless, it seems it has potential value beyond HSAIL and so
    I've kept it, it can of course always be easily removed in the
    future of GCN folk abandon it too.

  - I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
    need to stay indefinitely too just so that no future offload
    target picks that number.

  - I have kept dg-require-effective-target
    offload_device_nonshared_as requirement of thests which have it.

It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.
