Artem Savkov 720768767d Switch to per-file lookup table pointers.
So far create-diff-object worked only with objectfiles built from a
single source file. To support object-files built from multiple sources
such as linked vmlinux.o, we call locals_match() for each of STT_FILE
symbols and store the pointer to the beginning of appropriate symbol
block in lookup table in each symbol.
