We have 2 DumpStyles currently:
class GNUStyle : public DumpStyle<ELFT> and class LLVMStyle : public DumpStyle<ELFT>.
The problem of DumpStyle interface is that almost for each method
we provide const ELFFile<ELFT> * as argument. But in fact each of
dump styles keeps ELFDumper<ELFT> *Dumper which can be used to get an object from.
But since we use the Obj too often, I've decided to introduce a one more reference member
instead of reading it from the Dumper each time:
const ELFFile<ELFT> &Obj; This is kind of similar to FileName member which we have already:
it is also used to store a the file name which can be read from Dumper->getElfObject()->getFileName().
I had to adjust the code which previously worked with a pointer to an object
and now works with a reference.
In a follow-up I am going to try to get rid of const ELFObjectFile<ELFT> arguments
which are still passed to a set of functions.
