c0a14c1622 give StringMap a new ctor which allows you to initialize it 
with an existing allocator.  The interesting use case of this
is that it allows "StringMap<whatever, BumpPtrAllocator&>" for
when you want to allocate out of a preexisting bump pointer
allocator owned by someone else.

749ca32da1 eliminate the TargetInstrInfo::GetInstSizeInBytes hook. 
ARM/PPC/MSP430-specific code (which are the only targets that
implement the hook) can directly reference their target-specific
instrinfo classes.

336734aca6 Add new RegionInfo pass. 
The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".

093cb79d4b 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).

da9220bbef 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.

43aa8f03c1 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.

979634bbb0 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.

81781220d2 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.

0edf6a1131 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.
