This was only used for checking if is_shared/is_private were legal,
which we're not bothering to do anymore.
This is apparently visible to more than the target attribute (which
seems to silently ignore unrecognized features), so this has the
potential to break something (i.e. see the OpenMP test change)
This patch changes the kernels generated by OpenMP to have protected
visibility. This is unlikely to change anything functionally. However,
protected visibility better matches the behaviour of these GPU kernels.
We do not expect any pending shared library load to preempt these
kernels so we can specify a more restrictive visibility.

Currently the device kernels all have weak linkage to prevent linkage
errors on multiple defintions. However, this prevents some optimizations
from adequately analyzing them because of the nature of weak linkage.
This patch replaces the weak linkage with weak_odr linkage so we can
statically assert that multiple declarations of the same kernel will
have the same definition.

Passing any feature in the device-isa trait which is not supported by the host
was causing a compilation failure.
