The implementation is copied from HCC runtime.
For hcc it has no effect since apps can find them in either hcc runtime or HIP
runtime.
hip-clang needs it in HIP/HCC runtime so that HIP/HCC and HIP/VDI runtime are
swappable.
Add HIP_COMPILER to hipConfig, so that HIP packages built with HIP_COMPILER for HIP-Clang will be known during runtime by hipcc. Also add default locations to check for llvm and device-libs.
Move remaining function definitions from device_util.cpp to hip_runtime.h header. We can now remove the static library completely as device_util.cpp was the last file part of target hip::hip_device .
The state of HIP_COMPILER is not passing into config files, therefore config files cannot use if statements to determine dependency. For HIP-Clang, we should remove find_dependency(hcc), so we create separate config files depending on compiler path. This fixes issue in apps that uses hip-config.cmake.
Move all Integer Intrinsics, device_functions.cpp definitions and HIP specific device functions into HIP headers. Implement the device functions using llvm_intrinsics and device-libs functions instead of calling hc::__* functions. Remove device_functions.cpp since everything is now defined in header.
- Added a new target "clangformat" which formats the code using the
clang-format tool found in HCC package.
- Renamed target "static_check" to "cppcheck".
- Use find_program() macro to make the build system more robust.

See [the documentation](https://cmake.org/cmake/help/v3.0/command/find_package.html)
for exactly how the search procedure works. If you want to use an
LLVM from a specific location, use CMAKE_PREFIX_PATH as normal.
No longer do we have a nonstandard HIPIFY_CLANG_LLVM_DIR variable
for people to learn about.
Instead of deciding whether to build hipify-clang based on
the presence of an LLVM path on the command line, have an
explicit option.
Do we want this default-on or default-off? I've defaulted it to
on for now, but maybe we want the opposite?
Cmake cache was being rebuilt on each build. This was being done
to update HIP_VERSION, HCC_VERSION, .hipInfo and .hipVersion.
However, rebuilding cache also re-runs HIT parser which is slow.
Removing the cache rebuild should speed up the build. But user
needs to explicitly rebuild the cache in case HIP_VERSION or
HCC_VERSION changes by calling "make rebuild_cache"
