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. Change-Id: I2d10c60ce2bce846218c3ac6dc22a54bc6627919
