Extra offset added to the reference inside 'fromSymbol'
For example on x86_64 direct RIP-relative call instruction is 0xE8 0xNN 0xNN 0xNN 0xNN
where 0xNN 0xNN 0xNN 0xNN is offset between address of next instruction and callee.
Fixup address is (fromSymbol_address + refOffset)
Fixup offset is calculated as (referencedSymbol_address - (fromSymbol_address + refOffset + extraOffset))
In call example extraOffset = 4
