ARM code size optimisation: rewrite  __aeabi_dcmplt and __aeabi_dcmpgt (and also the less/greater equal variants) to __aeabi_cdcmple and _aeabi_cdrcmple, which avoids pulling in more helper functions from the math library during link time, and also cdcmple and cdrcmple are one and the same function (the latter just swaps the operands).
