Add the option -objc-meta-data to llvm-objdump used with -macho to
print the Objective-C runtime meta data for Mach-O files.

There are three types of Objective-C runtime meta data, Objc2 64-bit,
Objc2 32-bit and Objc1 32-bit. This prints the first of these types. The
changes to print the others will follow next.

[MCInstPrinter] Enable MCInstPrinter to change its behavior based on the
per-function subtarget.

Currently, code-gen passes the default or generic subtarget to the constructors
of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which
enables some targets (AArch64, ARM, and X86) to change their instprinter's
behavior based on the subtarget feature bits. Since the backend can now use
different subtargets for each function, instprinter has to be changed to use the
per-function subtarget rather than the default subtarget.

This patch takes the first step towards enabling instprinter to change its
behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to
AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the
various print methods table-gen auto-generates.

I will follow up with changes to instprinters of AArch64, ARM, and X86.

with this change. Printing of other section types will be added next.

Slightly refactor things for llvm-objdump and the -macho option so it can be used with
options other than just -disassemble so that universal files can be used with other
options combined with -arch options.

No functional change to existing options and use. One test case added for the
additional functionality with a universal file an a -arch option.

Re-add support to llvm-objdump for Mach-O universal files and archives with -macho
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.

Object/COFF: Fix off-by-one error for object having lots of relocations

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.

Object, COFF: Tighten the object file parser

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.

Pass an ArrayRef to MCDisassembler::getInstruction.

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.
