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. As we use holder data structure, we move all the cmp, math, cvt apis to cpp file
2. All the tests passed
3. Add more extensive testing for half

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
