Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.

Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change.

Use higher level functions in llvm-objdump.

This matches the rest of llvm-objdump better and isolates it from upcoming
changes to ELFFile.

Convert getSymbolSection to return an ErrorOr.

This function can actually fail since the symbol contains an index to the
section and that can be invalid.

[llvm-objdump] Add missing call to exit(1).

Reported by: Rafael Espindola.

Previously we kept going on partly corrupted input, which might result
in garbage being printed, or even worse, random crashes.

[llvm-objdump] Call exit(1) on error, i.e. fail early.

Previously we kept going on partly corrupted input, which might result
in garbage being printed, or even worse, random crashes.
Rafael mentioned that this is the GNU behavior as well, but after some
discussion we both agreed it's probably better to emit a reasonable
error message and exit. As a side-effect of this commit, now we don't
rely on global state for error codes anymore. objdump was the last tool
in the toolchain which needed to be converted. Hopefully the old behavior
won't sneak into the tree again.

[llvm-objdump] Add -D and --disassemble-all flags that attempt disassembly on all sections instead of just text sections.

Add missing 'const'. I don't think this is strictly required, but some
compiler configuration is giving me an error and it seems to be
recommended anyway.

llvm-objdump: Replace the -macho -raw option with a generic -raw-clang-ast
option that works with all object container formats.
Now that clang modules/PCH are object containers this option is useful to
to construct pipes like

llvm-objdump -raw-clang-ast foo.pcm | llvm-bcanalyzer -

to inspect the AST contents in a PCH container.
Will be tested via clang.

Belatedly addresses review feedback for r233390.

GNU binutils provides this behavior. objdump -r doesn't really help

It can fail trying to get the section on ELF and COFF. This makes sure the

This function can really fail since the string table offset can be out of

Return ErrorOr from getSection.

This also improves the logic of what is an error:

* getSection(uint_32): only return an error if the index is out of bounds. The
index 0 corresponds to a perfectly valid entry.
* getSection(Elf_Sym): Returns null for symbols that normally don't have
sections and error for out of bound indexes.

In many places this just moves the report_fatal_error up the stack, but those
can then be fixed in smaller patches.
