Comment (by jcowgill):

 I think in the old float_dsp test, only the "best" asssembly for the
 current processor was tested, whereas in checkasm all variations are
 tested. On AArch64, VFP is never the "best" because NEON will always be
 present, so I don't think VFP was ever being tested on AArch64 before the
 test was ported to checkasm.
