Summary: According to the ACLE spec, "__ARM_FEATURE_FMA is defined to 1 if the hardware floating-point architecture supports fused floating-point multiply-accumulate". This changes clang's behaviour from emitting this macro for v7-A and v7-R cores to only emitting it when the target has VFPv4 (and therefore support for the floating point multiply-accumulate instruction).
