reinterpret_cast<> doesn't create an object, so the texref is actually unitiliazed. This may lead to garbage data in some of its struct members.
Initialize it by performing a placement new. The constructer should set all of its members to default values. There's no way currently to extract the channel type, so use single channel char for now.

HIP assumes that image width is in bytes, but VDI assumes that image width in pixels. Need to perform byte -> pixel coversion before doing anything.

~45% to 50% of Performance drop on rocBLAS_int8 test
Enable cudaSetDeviceFlags() api call. Use active wait by default
for all devices.

Incoming changes from upstream split the struct hipMemcpy3DParms into two separate ones - hipMemcpy3DParms and HIP_MEMCPY3D, which are cudaMemcpy3DParms and CUDA_MEMCPY3D equivalents respectively.
Note that HIP_MEMCPY3D is missing half the members of CUDA_MEMCPY3D (this should be fixed in PR#1887). Work around this by using a substitute _HIP_MEMCPY3D struct for now.

Add hip::syncStreams(dev) to sync blocking streams on a given device.
hip::syncStreams(void) should only sync streams on the current device.

If a user passes a ptr that was allocated by hipMalloc(), the offset is guaranteed to be 0 and NULL may be passed as the offset parameter. We shouldn't return an error in this case.

Also make D2H and H2D keep track of the chain of events
when we need to use a different HostQueue.

The current texture implementation is based off the one for HIP-HCC. There's a lot of problems with it - only creating images from buffers, hard coding logic and ignoring user parameters. This leads to a whole lot of UB even with simple examples (as seen with RedShift's code).
This CL is aimed to bring the HIP-VDI texture implementation closer to what is described by Cuda.
hipMemcpyAtoA() - image to image copy.
hipMemcpyHtoA()/hipMemcpyDtoA() - buffer to image copy.
hipMemcpyAtoH()/hipMemcpyAtoD() - image to buffer copy.
hipArrayCreate()/hipArray3DCreate()/hipMallocArray()/hipMalloc3DArray() - creates 1D/2D/3D/1D Array/2D Array images.
hipCreateTextureObject() - creates sampler, (optional) creates 1D/2D image from buffer, (optional) creates image views.
hipBindTexture() - creates 1D image from buffer (should create a typed buffer, however this is not compatible with HIP-HCC).
hipBindTexture2D() - creates 2D image form buffer.
hipBindTextureToArray() - creates image view.
hipTexRefSetAddress() - creates 1D image from buffer (should create a typed buffer, however this is not compatible with HIP-HCC).
hipTexRefSetAddress2D() - creates 2D image from buffer.
hipTexRefSetArray() - creates image view.
There are still a lot of TODOs in the code, here's a few important ones:
1. VDI doesn't support a lot of sampler flags.
2. VDI doesn't support device to image 2D/3D copy.
3. Mipmaps implementation is incomplete.
4. Image view implementation is incomplete.

The current implementation of surd2D{read/write} directly addresses into
the image buffer via the hipArray::data ptr. This is incorrect to do
since we don't know the layout of the image. Also with VDI we won't have
access to the underlying image buffer.
Disable the surface api untill the device functions are switched to
using __ockl_image_{load/store}().

And also don't optimize the case where start==stop event to compute
elapsed time since the command can be a NDRange one.
HIP directed test will need to be fixed for that.
