Kevin Enderby 63cb9b07be Fix a bug in llvm-objdump when disassembling using the wrong default CPU
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
