Started adding native half math library support

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 Change-Id: Ic37859b2688ebb02e168bab643d1882bf4727952
