This patch removes edges in the scheduling graph between stores/loads off the same base register if memory accesses do not overlap. An improvement on eembc/automark on a cortex-a53 device, as well as a small improvement on spec2000/eon. No significant performance changes were observed on cortex-a57, but this may be more relevant on in-order architectures. Please have a look.
(I submitted on behalf of Sanjin to ease review.)
