84e9de4a58 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

9ec640a902 This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

cd3aa9d1ff rename getMDKind -> getMDKindID, make it autoinsert if an MD Kind 
doesn't exist already, eliminate registerMDKind.  Tidy up a bunch
of random stuff.

4e96d36f72 handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a 
compare.  On other targets we end up with a call to memcmp because we don't
want 16 individual byte loads.  We should be able to use movups as well, but
we're failing to select the generated icmp.

5d3919d5f9 move an optimization for memcmp out of simplifylibcalls and into 
SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.

47b4d6387f Remove minimal CFG sanity checks from verifier. 
These checks would often trigger on unreachable statements inserted by
bugpoint, leading it astray.

It would be nice if we could distinguish unreachable blocks from errors.

fc4c238bd5 Add more plumbing. This time in the LowerArguments and "get" functions which 
return partial registers. This affected the back-end lowering code some.

Also patch up some places I missed before in the "get" functions.

64d9eb0c06 Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint. 
This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals.
