[RFC] Add support for printing pdata for x86_64 pe coff objects

[Pierre Muller]

Hi Nicholas,

  thanks for the approval...
The problem is that my patch doesn't seem to work correctly anymore :(
This seems at least partially related to your recent fix for 
PR 17512.
  
  Firstly, the check for a zero size is before the
code that I added to support PE object for which size is first zero,
but virtual size must be used instead.
 But even after moving the check, I still get only part
of unwind code, while most is simply replaced by
"Too many unwind codes ("...
messages.

  This happen while simply trying to display pdata from
windres.o just as complied in binutils build directory for
x86_64-w64-mingw32
using cygwin environment.
  It also happens for ./objdump -p ./objdump.exe
which represents a regression as compared to previous behavior.


  Did you test my patch after your commit?
But, after testing, it appears that even pristine git shows the same
problem..

I don't know what I should do...

Pierre
