Implement 64-bit atomic ops for ARMv6K+. This implements the "quasi-atomic" 64-bit operations using LDREXD/STREXD when those instructions are available (e.g. our ARMv7-A devices). Also, folded in an expanded version of AtomicSpeed.c that has been floating around my hard drive for a while. (This time, without Condition Code Roulette.)
