1. As in hipModuleLaunchKernel(..., kernelParams, nullptr); works with this commit
2. Added headers AMDGPUPTNote.h, AMDGPURuntimeMetadata.h to do code object meta data parsing
3. Changed CMake to look at llvm link libraries
4. HIP developer should set env variable LLVM_HOME to remove link errors
5. HIP depends on installed LLVM (not source, not build)
6. Added sample to test out the feature
7. Right now HCC does not support embedding metadata in code object. Use clang opencl
8. Changed HIPCC to read LLVM_HOME env var
9. New argument to CMake should be given -DLLVM_HOME=<where llvm 5.0 is installed>

Use __device__ for all variables and functions to be used in kernel path
Abolish __device and adopt [[hc]] in HIP implementation, so __device__ can be
used on all HIP applications, no matter they are variables or functions.

XXX FIXME get around LDS spills caused in Promote-free HCC
hipDynamicShared2 uses all 64KB of LDS for computation. But in Promote-free HCC
there are cases where LDS spills would occur, which would make the test case to
hang.
In this workaround commit we reduce the size of dynamic LDS used to get around
this known issue, and will revert this commit when LDS spills are resolved in
HCC.

Changes to cope with Promote-free HCC
- abolish usage of address_space GNU attribute
- use __device in file-scope global variables which would be accessed by GPU kernels
- temporarily disable some math functions which take pointer arguments

+ all Cuda 7.5 RT API enum values are synced.
+ a few missing functions are added.
+ CONV_EXEC type is added for Execution control functions and data types.
+ in hipMemcpyDtoDAsync: cuMemcpyDtoD -> cuMemcpyDtoDAsync
+ in hipMemcpyDtoHAsync: cuMemcpyDtoH -> cuMemcpyDtoHAsync
P.S.
"The types CUstream and cudaStream_t are identical and may be used interchangeably", thus explicit c-like type cast is not needed, aka CUstream(stream).
