fc3ee085a0 Disallow null as a named metadata operand. 
Make MDNode::destroy private.
Fix the one thing that used MDNode::destroy, outside of MDNode itself.

One should never delete or destroy an MDNode explicitly. MDNodes
implicitly go away when there are no references to them (implementation
details aside).

b0db34a612 Use TrackingVH instead of WeakVH for NamedMDNode's operands, since nodes 
referenced by NamedMDNodes shouldn't be deleted.

79c7edd75f Added support to MachO.h for many defines and structures that are needed 
to Parse mach-o files. All defines have been renamed to not conflict with
#defines in mach header files, all structures were left named the same but
are in the llvm::MachO namespace.

b9a28557ea Add support for remapping metadata kind IDs when reading in a 
bitcode file, so that two bitcode files where the same metadata kind
name happens to have been assigned a different ID can still be
linked together.

Eliminate the restriction that metadata kind IDs can't be 0.

Change MD_dbg from 1 to 0, because we can now, and because it's
less mysterious that way.

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.

5f218b8612 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch 
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

522ef60c01 Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented 
linked list.  This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

cecae7f56c Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64. 
This property will be used by the register pressure tracking instruction scheduler.

f58b5d7ad0 TblGen/AsmMatcher: Add support for honoring instruction Requires<[]> attributes as part of the matcher.

150021561c Target: Give the TargetAsmParser access to the TargetMachine.
