ARM64 hardware expects 64bit aligned address for watchpoint invocation. However, it provides byte selection method to select any number of consecutive byte set within the range of 1-8.
This patch adds support to test all such byte selection option for different memory write sizes.
Patch also adds a test for handling the case when the cpu does not report an address which exactly matches one of the regions we have been watching (which is a situation permitted by the spec if an instruction accesses both watched and unwatched regions). The test was failing on a MSM8996pro before this patch series and is passing now.
