[ARM] Fix Tag_ABI_HardFP_use build attribute
Fix Tag_ABI_HardFP_use build attribute to handle single precision FP, replace deprecated Tag_ABI_HardFP_use value of 3 with 0 and also add some tests for Tag_ABI_VFP_args. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193856 91177308-0d34-0410-b5e6-96231b3b80d8
