Cent OS 7 has conflicts between its libc++ and libstdc++. Seems that we cannot use libstdc++ on Cent OS. This is related to SWDEV-131972 [ROCm CQE][Cent OS 7][G] Building any HIP sample giving an fatal error: 'bits/c++config.h'.
- Refactoring introduced a bug when user does not specify any target via
--amdgpu-target, but has an invalid target specified in
HCC_AMDGPU_TARGET. In this case the selection logic was defaulting to
gf803.
- Removed defaulting to any specific target if rocm_agent_enumerator
fails. hipcc will report this and die if linking was required.

Existing logic has a bug. If user specifies targetA via commandline
options, while enumerator returns targetB, hipcc will create a fatbin
containing targets targetA and targetB. enumerator should only be used
when no target is specified by user (commandline or env var).

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>

only force to libstdc++ if the g++ is older than version 5 since hcc already defaults to libstdc++ with newer g++

force include libstdc++ headers and stdc++ only if g++ version < 5 since hcc uses libstdc++ by default if g++ > 5 is present

(cherry picked from commit 866e744e40cf1378af8a679b54959bf5226c340f)
1. Split hip_ir.ll to hip_hc.ll and hip_hc_gfx803.ll
a. hip_hc.ll contains arch generic ir implementations
b. hip_hc_gfx803.ll contains gfx803 (fiji, polaris) specific ir
2. HIPCC can now parse --amdgpu-target=*.
a. Usage: hipcc --amdgpu-target=gfx803 --amdgpu-target=gfx701
b. TODO: Convert to --amdgpu-target=gfx803,gfx701
3. With LLC in HCC able to generate native f16 isa, removed inline half asm math ops
4. Fixed threadfence and threadfence_block to use functions in rocdl

1. Removed HIP_EXPERIMENTAL env variable so that device code will be accessed from LLVM IR
2. Removed soft support from headers and moved to hip_fp16.cpp
3. Added LLVM IR + inline asm to hip_ir.ll
4. Added test for fp16
5. Added barriers for hcc 3.5 and hcc 4.0 for half support
a. Which means, hcc 4.0 can parse __fp16 but hcc 3.5 cant
b. HCC 4.0 code is implemented now, hcc 3.5 will be added later

hipcc accepts new parameter -use-staticlib and -use-sharedlib to
control linking behavior. Default is still static library.

1. Use -DHIP_FAST_MATH to make precise math functions compiled to fast math
2. Added double fast math functions for sqrt
3. Changed hipcc to parse -use_fast_math (not working)
4. Added passed tag to hipFloatMath test

Users who desire otherwise can set HIP_ATP_MARKER=0.
Also remove old unused hipcc_explicit_lib option.
