[AIX][XCOFF][Patch2] decode vector information and extent long table of the traceback table of the xcoff.

SUMMARY:

1. decode the Vector extension if has_vec is set
2. decode long table fields, if longtbtable is set.

There is conflict on the bit order of HasVectorInfoMask and HasExtensionTableMask between AIX os header and IBM aix compiler XLC.
In the /usr/include/sys/debug.h defines
static constexpr uint32_t HasVectorInfoMask = 0x0040'0000;
static constexpr uint32_t HasExtensionTableMask = 0x0080'0000;
but the XLC defines as

static constexpr uint32_t HasVectorInfoMask = 0x0080'0000;
static constexpr uint32_t HasExtensionTableMask = 0x0040'0000;
we follows the definition of the IBM AIX compiler XLC here.

[AIX][XCOFF][Patch1] Provide decoding trace back table information API for xcoff object file for llvm-objdump -d

SUMMARY:

1. This patch provided API for decoding the traceback table info and unit test for the these API.

2. Another patchs will do the following things:
2.1 added a new option --traceback-table to decode the trace back table information for xcoff object file when
using llvm-objdump to disassemble the xcoff objfile.

2.2 print out the traceback table information for llvm-objdump.

[llvm-objdump][XCOFF] Use symbol index+symbol name + storage mapping class as label for -D

SUMMARY:

For the llvm-objdump -D, the symbol name is used as a label in the disassembly for the specific address (when a symbol address is equal to the virtual address in the dump).

In XCOFF, multiple symbols may have the same name, being differentiated by their storage mapping class. It is helpful to print the QualName and not just the name when forming the output label for a csect symbol. The symbol index further removes any ambiguity caused by duplicate names.

To maintain compatibility with the binutils objdump, the XCOFF-specific --symbol-description option is added to enable the enhanced format.

[XCOFF] Fix link errors from explicit template instantiation

I happen to be using clang-cl+lld-link locally, and I get these link
errors:

>>> tools\llvm-readobj\CMakeFiles\llvm-readobj.dir\XCOFFDumper.cpp.obj:(public: virtual void __cdecl `anonymous namespace'::XCOFFDumper::printSectionHeaders(void))

I suspect this is because the explicit template instaniation appears
before the inline method definitions in the .cpp file, so they aren't
available at the point of instantiation. Move the explicit instantiation
later.

Also, forward declare the explicit instantiation for good measure.
