Refactor instprinter and mcdisassembler to take a SubtargetInfo. Add -mattr= handling to llvm-mc. Reviewed by Owen Anderson.

llvm-svn: 139237

Move TargetRegistry and TargetSelect from Target to Support where they belong.
These are strictly utilities for registering targets and components.

llvm-svn: 138450

Some refactoring so TargetRegistry.h no longer has to include any files
from MC.

Add MCInstrAnalysis class. This allows the targets to specify own versions of MCInstrDescs functions.

- Add overrides for ARM.
- Teach llvm-objdump to use this instead of plain MCInstrDesc.

llvm-objdump: Use help of CFG to print assembly when --cfg is passed.

This way we can avoid printing unreachable code (data).

InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

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.

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.

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!
