Parsing of __init_offsets section in MachO

[mostobriv]

What is the feature you'd like to have?
As for some time apple presented new ways to store global constructors pointers, modern compilers used to add the sections __init_offsets (pointers there stored as 32-bit RVA) instead of an old one __mod_init_func (pointers there stored as raw pointers), i think BN should be able to parse it as well and use it within its analysis.

Is your feature request related to a problem?
Not much, just simple enhancement

Are any alternative solutions acceptable?
It can be easily done with scripting yeah.

Additional Information:
There is dyld code, related to getting initialisers from this section:
