The only thing left is LEB printing, which uses EmitRawText
for now.

representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

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
on top of MC.

Do not eagerly record known previous location. DBG_VALUE may not cause a new label due to one or other reason.

Debug info can now properly represent functions inside classes inside other functions.  Partial fix for Radar 7424645.

POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.
