ARM: correct handling of .fpu directive The FPU directive permits the user to switch the target FPU, enabling instructions that would be otherwise unavailable. However, when configuring the new subtarget features, we would not enable the implied functions for newer FPUs. This would result in invalid rejection of valid input. Ensure that we inherit the implied FPU functionality when enabling newer versions of the FPU. Fortunately, these are mostly hierarchical, unlike the CPUs. Addresses PR22395. llvm-svn: 227584
