Kevin Enderby 1025e9e9d6 Add printing the LC_LINKER_OPTION load command with llvm-objdump’s -private-headers.
Also corrected the name of the load command to not end in an ’S’ as well as corrected
the name of the MachO::linker_option_command struct and other places that had the
word option as plural which did not match the Mac OS X headers.

Rafael Espindola c0e334099c Move three methods only used by MCJIT to MCJIT.
These methods are only used by MCJIT and are very specific to it. In fact, they
are also fairly specific to the fact that we have a dynamic linker of
relocatable objects.

Kevin Enderby 957d027c5e Remove the static version of getScatteredRelocationType() now that r221211 added
a public version MachOObjectFile::getScatteredRelocationType().

This should fix the build bot for the unused function error.

Benjamin Kramer 5ea04462dc [Object] Fix MachO's getUuid to return a pointer into the object instead of a dangling ArrayRef.
This works because uuid's are always little endian so it's not swapped.

Alexander Potapenko 4976a53fb7 Add MachOObjectFile::getUuid()
This CL introduces MachOObjectFile::getUuid(). This function returns an ArrayRef to the object file's UUID, or an empty ArrayRef if the object file doesn't contain an LC_UUID load command.
The new function is gonna be used by llvm-symbolizer.

Rafael Espindola 8175be535a Remove bogus std::error_code returns form SectionRef.
There are two methods in SectionRef that can fail:

* getName: The index into the string table can be invalid.
* getContents: The section might point to invalid contents.

Every other method will always succeed and returning and std::error_code just
complicates the code. For example, a section can have an invalid alignment,
but if we are able to get to the section structure at all and create a
SectionRef, we will always be able to read that invalid alignment.

Nick Kledzik 367cf70f27 [llvm-objdump] for mach-o add -bind, -lazy-bind, and -weak-bind options
This finishes the ability of llvm-objdump to print out all information from
the LC_DYLD_INFO load command.

The -bind option prints out symbolic references that dyld must resolve 
immediately.

The -lazy-bind option prints out symbolc reference that are lazily resolved on 
first use.

The -weak-bind option prints out information about symbols which dyld must
try to coalesce across images.

Nick Kledzik a240fc5cb9 [llvm-objdump] support -rebase option for mach-o to dump rebasing info
Similar to my previous -exports-trie option, the -rebase option dumps info from
the LC_DYLD_INFO load command. The rebasing info is a list of the the locations
that dyld needs to adjust if a mach-o image is not loaded at its preferred 
address. Since ASLR is now the default, images almost never load at their
preferred address, and thus need to be rebased by dyld.

Kevin Enderby 37598b62a7 Adds the next bit of support for llvm-objdump’s -private-headers for executable Mach-O files.
This adds the printing of more load commands, so that the normal load commands
in a typical X86 Mach-O executable can all be printed.
