[ARM] Add test to check pcs of ARM ABI runtime floating point helpers
The ARM Runtime ABI document (IHI0043) defines the AEABI floating point helper functions in section 4.1.2 The floating-point helper functions. The functions listed in this section must always use the base AAPCS calling convention. This test generates calls to all the helper functions that llvm supports and checks that the base AAPCS calling convention has been used. We test the equivalent of -mfloat-abi=soft, -mfloat-abi=softfp, -mfloat-abi=hardfp with an FPU that supports single and double precision, and one that only supports double precision.
