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 Change-Id: Ic9a9e3e04139b0d75d2c2a263c030ca77adc1019
