[ARM] Enable VFP to be built when non-VFP capable CPUs are selected
Since we pass flags to the compiler to control code generation based on the least capable selected CPU, if we want to include VFP support, we must tweak the assembler flags to allow the VFP instructions. Moreover, we must not use the mrrc/mcrr versions since these will not be recognised by the assembler. We do not convert all instructions to the VFP-equivalent (yet) since binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any other way (other than using the mrc equivalent) to encode this instruction - which is rather a problem when you have a VFP implementation which requires these instructions.
