5d8c7d0d36 MC: Add support for disabling "temporary label" behavior. Useful for debugging 
on Darwin.

a2eec46242 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.

- Don't leak parsed operands during tokenization.
- Don't leak printed insts in llvm-mc.

operand.evaluate as an error code, not as the
contents of the operand.

f9e09104f1 Make tool_output_file's raw_ostream instance a member variable instead 
of a base class.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.

bef725be86 Use the new tool_output_file in several tools. This fixes a variety 
of problems with output files being left behind or output streams
being left unclosed. Fix llvm-mc to respect the -o option in all
modes, rather than hardcoding outs() in some cases.

1ac58ea0f3 start straightening out libedis's dependencies and make it fit 
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes. 

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

150021561c Target: Give the TargetAsmParser access to the TargetMachine. 
- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

5d40d53cab Currently, createMachOStreamer() is invoked directly in llvm-mc which 
isn't ideal if we want to be able to use another object file format.

Add a createObjectStreamer() factory method so that the correct object
file streamer can be instantiated for a given target triple.

033fde84b5 Second try at integrating the edis tester. This 
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

d04906b49e llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always need 
exactly two passes in that case, and don't ever need to recompute any layout,
so this is a nice baseline for relaxation performance.
