Benjamin Kramer 5d173c0dab llvm-objdump: Use help of CFG to print assembly when --cfg is passed.
This way we can avoid printing unreachable code (data).

Evan Cheng f60768a14e Fix last bits of MC layer issues. llvm-mc doesn't need to initialize TargetMachine's anymore.

Evan Cheng 8c886a40d2 Combine all MC initialization routines into one. e.g. InitializeX86MCAsmInfo,
InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

Chandler Carruth 2d71c421f9 Move the registered target printing in version strings completely out of
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.

The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

Benjamin Kramer 87ee76ca73 Sketch out an CFG reconstruction mode for llvm-objdump.
- Not great yet, but it's a start.
- Requires an object file with a symbol table. (I really want to fix this, but it'll need a whole new algorithm)
- ELF and COFF won't work at the moment due to libObject shortcomings.

To try it out run
$ llvm-objdump -d --cfg foo.o

This will create a graphviz file for every symbol in the object file's text section containing a CFG.

Evan Cheng 2129f59637 Introduce MCCodeGenInfo, which keeps information that can affect codegen
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

Evan Cheng fe6e405e8c Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

Bill Wendling 00f0cddfd4 We need to pass the TargetMachine object to the InstPrinter if we are printing
the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.
