Rafael Espindola e883514736 Fix printing of 64 bit values and make test more strict.

Davide Italiano 26fabd7ac5 [llvm-readobj/MachO] Ensure we always have valid CmdName/SegmentName. 
Otherwise we might end up printing garbage while dumping.

Davide Italiano 096cda11fc [llvm-readobj] Fix another "time of check to time of use bug".

Davide Italiano 9a429b766f [llvm-readobj] MachO -- dump LinkerOptions load command. 
Example output:

Linker Options {
  Size: 32
  Count: 2
  Strings [
    Value: -framework
    Value: Cocoa
  ]
}

There were only two tests using this -- so I converted them as part of
this commit rather than separately.

Rafael Espindola 7d250f773f Pass a symbol table to getRelocationSymbol instead of returning one. 
This removes a report_fatal_error from library and avoids checking a
section property for every section entry.

Rui Ueyama 71ba9bdd23 Re-apply r246276 - Object: Teach llvm-ar to create symbol table for COFF short import files 
This patch includes a fix for a llvm-readobj test. With this patch, 
the tool does no longer print out COFF headers for the short import
file, but that's probably desirable because the header for the short
import file is dummy.

Rafael Espindola aae5541455 Don't iterate over all sections in the ELFFile constructor. 
With this we finally have an ELFFile that is O(1) to construct. This is helpful
for programs like lld which have to do their own section walk.

Rafael Espindola 8bab889b0f Convert getSymbolSection to return an ErrorOr. 
This function can actually fail since the symbol contains an index to the
section and that can be invalid.

Rafael Espindola 8b3b09fdcf Move to llvm-readobj code that is only used there. 
lld might end up using a small part of this, but it will be in a much
refactored form. For now this unblocks avoiding the full section scan in the
ELFFile constructor.

This also has a (very small) error handling improvement.
