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.

with fixes. Includes the move of tests for llvm-objdump for universal files to an X86
directory. And the fix where it was failing on linux Rafael tracked down with asan.
I had both Jim Grosbach and Adam Hemet look over the second fix since I could not
set up asan to reproduce with the old version but not with the fix.

llvm-objdump printed out an error message for this off-by-one error,
but because it always exits with 0 whether or not it found an error,
the test (llvm-objdump/coff-many-relocs.test) succeeded.
I made llvm-objdump exit with EXIT_FAILURE when an error is found.

We were a little lax in a few areas:
- We pretended that import libraries were like any old COFF file, they
are not. In fact, they aren't really COFF files at all, we should
probably grow some specialized functionality to handle them smarter.
- Our symbol iterators were more than happy to attempt to go past the
end of the symbol table if you had a symbol with a bad list of
auxiliary symbols.

FYI, removed the unused MCInstrAnalysis as it does not exist for 64-bit ARM and
was causing a “couldn't initialize disassembler for target” error.

With this patch MCDisassembler::getInstruction takes an ArrayRef<uint8_t>
instead of a MemoryObject.
Even on X86 there is a maximum size an instruction can have. Given
that, it seems way simpler and more efficient to just pass an ArrayRef
to the disassembler instead of a MemoryObject and have it do a virtual
call every time it wants some extra bytes.

add the code and test cases for 32-bit ARM symbolizer.
Also fixed the printing of data in code as it was not using the table correctly
and needed to fix one of the test cases too.
This will break lld’s test/mach-o/arm-interworking-movw.yaml till the tweak
for that is made. Which I’ll be committing immediately after this commit.

DiceTableEntry is 24 bytes on my machine, it's probably better to pass
them by reference.
This fixes PR21464.

This prints disassembly comments for Objective-C references to CFStrings,
Selectors, Classes and method calls.

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.

So in fully linked images when a call is made through a stub it now gets a
comment like the following in the disassembly:
callq 0x100000f6c ## symbol stub for: _printf
indicating the call is to a symbol stub and which symbol it is for. This is
done for branch reference types and seeing if the branch target is in a stub
section and if so using the indirect symbol table entry for that stub and
using that symbol table entries symbol name.

get the literal string “Hello world” printed as a comment on the instruction
that loads the pointer to it. For now this is just for x86_64. So for object
files with relocation entries it produces things like:
leaq L_.str(%rip), %rax ## literal pool for: "Hello world\n"
and similar for fully linked images like executables:
leaq 0x4f(%rip), %rax ## literal pool for: "Hello world\n"
Also to allow testing against darwin’s otool(1), I hooked up the existing
-no-show-raw-insn option to the Mach-O parser code, added the new Mach-O
only -full-leading-addr option to match otool(1)'s printing of addresses and
also added the new -print-imm-hex option.
