Function was merging equal data even if they weren't adjecant. This caused a problem in command-disassemble.s test because the two ranges describing the function would be merged and "swallow" the function between them. This PR copies/adapts the algorithm from RangeVector::CombineConsecutiveEntries (which does not have the same problem) and also adds a call to ComputeUpperBounds as moving entries around invalidates the binary tree. (The lack of this call wasn't noticed until now either because we were not calling methods which rely on upper bounds (right now, it's only the ill-named FindEntryIndexes method), or because we weren't merging anything.
