Revise debug info machinery to digest nested functions and classes.
...
A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function. GCC presents the innermost
function to llvm-convert first. Heretofore, the debug info mistakenly
placed the inner function at module scope. This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested. Radar 7426545.

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.
