in the second slice of a Mach-O universal file.
The code in llvm-objdump in in DisassembleMachO() was getting the default
CPU then incorrectly setting into the global variable used for the -mcpu option
if that was not set. This caused a second call to DisassembleMachO() to use
the wrong default CPU when disassembling the next slice in a Mach-O universal
file. And would result in bad disassembly and an error message about an
recognized processor for the target:
% llvm-objdump -d -m -arch all fat.macho-armv7s-arm64
fat.macho-armv7s-arm64 (architecture armv7s):

Previously such relocations fell into the last case for local
symbols, using the relocation addend as symbol index, leading to
a crash.

in this case for CPU_SUBTYPE_ARM64_ALL.
For this cpusubtype it should default to a cyclone CPU
to give proper disassembly without a -mcpu= flag.

in llvm-objdump for Mach-O files add the printing of the
ARM_THREAD_STATE64 in the same format as
otool-classic(1) on darwin.
To do this the 64-bit ARM general tread state
needed to be defined in include/llvm/Support/MachO.h .

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.
