This remove the old DebugLoc class, making it a typedef for DebugLoc,

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before. Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT

and will replace the 'DbgInfo' member in Instruction.
The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24
bytes for the DbgInfo member in Instruction on a 32/64 bit system),
it means that we will end up not having to allocate MDNodes to
represent the "DILocations" in common cases of -O0 -g, and it is
much more efficient to get things out of than the MDNode.

the storage of !dbg metadata kinds in the instruction themselves.
The on-the-side hash table works great for metadata that not-all
instructions get, or for metadata that only exists when optimizing.
But when compile-time is everything, it isn't great.
I'm not super thrilled with the fact that this plops a TrackingVH in
Instruction, because it grows it by 3 words. I'm investigating
alternatives, but this should be a step in the right direction in any
case.
