Summary:
Merged the recently added `err_attribute_argument_negative` diagnostic
with existing `err_attribute_requires_positive_integer` diagnostic:
the former allows only strictly positive integer, while the latter
also allows zero.

Summary:
Negative arguments in kernel attributes are silently bitcast'ed to
unsigned, for example:
__attribute__((reqd_work_group_size(1, -1, 1)))
__kernel void k() {}
is a complete equivalent of:
__attribute__((reqd_work_group_size(1, 4294967294, 1)))
__kernel void k() {}
This is likely an error, so the patch forbids negative arguments in
several OpenCL attributes. Users who really want 4294967294 can still
use it as an unsigned representation.

There are HIP applications e.g. Tensorflow 1.3 using amdgpu kernel attributes, however
currently they are only allowed on OpenCL kernel functions.
This patch will allow amdgpu kernel attributes to be applied to CUDA/HIP __global__
functions.

Summary:
OpenCL access qualifiers are now not only used for image types, refine it to avoid misleading,
Add semacheck for OpenCL access qualifier as well as test caees.
