c69c29bc4b While calculating original type size for a derived type, handle type variants encoded as DIDerivedType appropriately.
This improves bitfield support.

093d35bd8a First bitcase use may not lead to a dbg.declare intrinsic. Iterate uses until one find's dbg.declare intrinsic.

ee9d2f0cc0 "there is not any instruction with attached debug info in this module" does not mean "there is no debug info in this module". :)

d47d348cdf It's possible for a global variable to be optimized out of a metadata object. So
we should allow a "null" with this dyn_cast.

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?

a3bce35a07 Add a way for a frontend to generate more complex dwarf location
information.  This allows arbitrary code involving DW_OP_plus_uconst
and DW_OP_deref.  The scheme allows for easy extention to include,
any, or all of the DW_OP_ opcodes.  I thought about just exposing all
of them, but, wasn't sure if people wanted the dwarf opcodes exposed
in the api.  Is that a layering violation?

With this scheme, the entire existing block scheme used by llvm-gcc
can be switched over to the new scheme.  I think that would be
cleaner, as then the compiler specific bits are not present in llvm
proper.  Before the old code can be yanked however, similar code in
clang would have to be removed.

Next up, more testing.

7d42bfab6c Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)
