Improve the handling of missing elf symtab and missing symbol sizes
* Generate artificial symbol names from eh_fame during symbol parsing
so these symbols are already present when we calcualte the size of
the symbols where 0 is specified.
* Fix symbol size calculation for the last symbol in the file where
it have to last until the end of the parent section.
This is the re-commit of the original change after fixing some test
failures on OSX.
