There are kinds of inline asm constraints and corresponding register class or register as following. 'b': mGPRRegClass 'v': sGPRRegClass 'w': sFPR32RegClass or sFPR64RegClass 'c': C register 'z': R14 register 'h': HI register 'l': LO register 'y': HI or LO register It also adds codegen test for inline-asm including constraints, clobbers and abi names.
