We don't need to print any of the special __mh_*_header symbols when
disassembling. Since they point at the beginning of the segment (not where the
actual code is) they're pretty misleading.
Should also fix lld bots.

Before we printed a warning to stderr and left the actual output stream in a
mess. This tries to print a .long or .short representation of what we saw (as
if there was a data-in-code directive).
This isn't guaranteed to restore synchronization in Thumb-mode (if the invalid
instruction was supposed to be 32-bits, we may be off-by-16 for the rest of the
function). But there's no certain way to deal with that, and it's invalid code
anyway (if the data really wasn't an instruction, the user can add proper
.data_in_code directives if they care)

Only one consumer (llvm-objdump) actually cared about the fact that there were
two triples. Others were actively working around the fact that the Triple
returned by getArch might have been invalid. As for llvm-objdump, it needs to
be acutely aware of both Triples anyway, so being generic in the exposed API is
no benefit.
Also rename the version of getArch returning a Triple. Users were having to
pass an unwanted nullptr to disambiguate the two, which was nasty.
The only functional change here is that armv7m and armv7em object files no
longer crash llvm-objdump.

using numeric values and not their symbolic constant names.
The routines that print Mach-O stuff already had a verbose parameter and this
change is just changing the passing true to passing !NonVerbose. With just a
couple of fixes and a bunch of test case updates.

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.

file with -macho, the Mach-O specific object file parser option.
After some discussion I chose to do this implementation contained in the logic
of llvm-objdump’s MachODump.cpp using a second disassembler for thumb when
needed and with updates mostly contained in the MachOObjectFile class.
