Devang Patel c5cc659cfa "there is not any instruction with attached debug info in this module" does not mean "there is no debug info in this module". :)

Bill Wendling 3dc625cdce 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.

Devang Patel 55571bd7bd Extract subprogram and compile unit information from the debug info attached to an instruction.

Mike Stump 70cb67fcf4 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?

Devang Patel 34986f12e6 Add another MDNode into DebugLocTuple. This will be used to keep track of inlined functions.

Mike Stump 14cf8ecf0b 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.

Daniel Dunbar 0356483539 Switch DIDescriptor to use a TrackingVH. - This makes it much safer to work with debug info, since it was extraordinarily easy to have dangling pointers thanks to MDNode uniquing.

Devang Patel f08e35d9dc Revert 79977. It causes llvm-gcc bootstrap failures on some platforms.

Devang Patel 02aac922b4 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!)

Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.
