Introduce the Dot functions which are available in the device library. Forward those prototypes, and introduce HIP API to expose the usage of the dot functions.

+ Append '--' to the end of hipify-clang options in case of its absence.
[Reason]
+ Avoid the necessity for the user in JSON compilation database specification.
Otherwise:
Error while trying to load a compilation database:
Could not auto-detect compilation database for file "test.cu"
Though the hipification will be performed correctly without JSON database.
[ROCm/hip commit: aa4c59ae0c]
Repeats clang's '--cuda-path' option.
[Reason]
In case of absence of any other clang's options setting '-cuda-path' allows not to specify separator '--' before clang's '--cuda-path'.
+ Tests and scripts are updated accordingly.
[ROCm/hip commit: fbfe005e4e]
A hash calculated via FNV-1a algorithm is introduced in ihipModule_t, the
internal of hipModule_t. The hash is used by HIP module APIs such as
- read_agent_global_from_module
to determine whether the agent-scope globals for a module have been iterated.
This commit fixes one issue that applications which load / unload modules
frequently would occasionally fail. After deep investigation of the issue it
turns out the old implementation in read_agent_global_from_module uses
hipModule_t as the key, which is not robust enough, as hipModule_t instances
are allocated dynamically so there are cases that one memory address may be
used by multiple hipModule_t instances. The real solution is to introduce a
uniquely identifiable hash for the code object associated with the HIP module.
And that's the rationale behind this commit.

hipify-clang could be built by Visual Studio 14 2015 or higher.
[Reason]
hipify-clang contains c++14 features which are not supported even by the latest VS 2013 and the Platform Toolset "Visual C++ Compiler Nov 2013 CTP".
[ROCm/hip commit: cd15a85663]
- Improved install instructions for AMD-hcc and NVIDIA-nvcc.
- Removed redundant section related to HCC-Native-GCN-ISA.

[ROCm/hip commit: b8c78f90a6]
Header files in those dirs are an integral part of clang, which includes wrapper headers for CUDA.
There is no need in checking those dirs.
[Reasons]
1. clang will not take into account empty or irrelevant include dirs;
2. Packages for different clang versions will have different header files in the above dirs.
[ROCm/hip commit: c519c89abf]
[Reasons]
+ We don't compile kernel code at least for now as HIP kernel syntax is almost equal CUDA's;
+ clang always includes PTX in its binaries, so e.g. a binary compiled with --cuda-gpu-arch= would be forwards-compatible with e.g. sm_35 GPUs.
[ROCm/hip commit: dec459efca]
+ Due to latest Windows SDK implementation based on c++14 features, '-std+c++14' is a must;
+ Doesn't affect older versions of MSVC 2017, 2015 (the latest supported is MSVC 2015);
+ On linux still '-std=c++11' is a must;
+ Exclude '-std=' from lit config.
[ROCm/hip commit: 2d3f62c3e1]
[Reasons]
+ File is opened further by clang
+ There is a regression with LLVM 5.x, when system error occurs: temporary file couldn't be renamed - permission denied.
