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.

4995bb0450 Start using DIFile. See updated SourceLevelDebugging.html for more information. 
This patch updates LLVMDebugVersion to 8.
Debug info descriptors encoded using LLVMDebugVersion 7 is supported.

Corresponding llvmgcc and clang FE commits are required.

c1b5223e76 Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast). 
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

2a16652946 Introduce the "@llvm.dbg.value" debug intrinsic. 
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

An example:
  call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.

532ed49e39 Expand api out in the usual inserter way, though, I do have a 
question, can we get rid of the BasicBlock versions of all inserters
and use Head == 0 to indicate the old case when GetInsertBlock == 0?
