When relocation points to symbol that is not defined within module mark
it as optional. When symbol is available at dynamic linking time then
info from the function is retrieved but when the symbol is not available
then ignore the dependency.
Any unresolved symbol needed for module linking is already handled
in a separate place.

This commit adds support for handling local symbols.
* Added 2 fields to SymbolInfo - binding, and associated
instructions segment id.
* Simplified code for decoding elf symbols and relocations.
* Simplified code for patching instruction segments.
* Changed logic of decodeElfSymbolTableAndRelocations:
* Add every global symbol to symbol map.
* Add any local symbol used by relocation to symbol map.
* Changed logic of link:
* After performing relocations remove local symbols from map.
* Replaced UNRECOVERABLE_IF with returning error.
* Removed LocalSymbolInfo structure used before for local kernel jumps.
* Removed old tests.
