MemoryObject *	getRegionFor (uint64_t Addr)
	Return a memory region suitable for reading starting at Addr. In most cases, this returns a StringRefMemoryObject backed by the containing section. When no section was found, this returns the FallbackRegion, if it is suitable. If it is not, or if there is no fallback region, this returns 0. More...
