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).

abbd9ae4d3 DebugInfoFinder::processModule was foiling my plot by 
materializing an MDNode for every debugloc.  don't do that! :)

"clang -g -S t.c" really no longer makes mdnodes for location 
tuples now.

305c84b8ee Switch the code generator (except the JIT) onto the new DebugLoc 
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.

c91ba40a59 Before inserting llvm.dbg.declare intrinsic at the end of a basic block, check whether the basic block has a terminator or not.
