Plumb in the ARM thumb symbolizer in llvm-objdump’s Mach-O disassembler and
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.
