b19f7964ea Add a new "NewDebugLoc" class which will eventually replace DebugLoc, 
and will replace the 'DbgInfo' member in Instruction.

The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24 
bytes for the DbgInfo member in Instruction on a 32/64 bit system),
it means that we will end up not having to allocate MDNodes to 
represent the "DILocations" in common cases of -O0 -g, and it is
much more efficient to get things out of than the MDNode.

f4aab98729 Re-add the Metadata.h include to LLVMContextImpl.h so that MDNode is complete 
where FoldingSet<MDNode> is instantiated.  Clang and MSVC complain; gcc
doesn't.

819ce89d8f Delete MDNodes when LLVMContext is destroyed. Previous attempts: r97918, r97788. 
Tested: clang debug bootstrap, llvm-gcc bootstrap, `make check-lit`
after configuring with --with-llvmgccdir (and this did run the
FrontendC* tests this time)

84e9de4a58 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

587962c667 Remove isPod() from DenseMapInfo, splitting it out to its own 
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

can be banging on a context at a time, this isn't needed.  Owen, please

27616c3c80 Now Bitcode reader bug is fixed. Reapply 80839.

097a206969 Free the constants that have no uses in ~LLVMContext. 
This fixes leaks from LLVMContext in multithreaded apps.
Since constants are only deleted if they have no uses, it is safe to not delete
a Module on shutdown, as many single-threaded tools do.
Multithreaded apps should however delete the Module before destroying the
Context to ensure that there are no leaks (assuming they use a different context
for each thread).

4af3f9b57d Allocate the basic types inside the LLVMContextImpl instance, 
rather than separately with new. Move the members above the
TypeMap members to avoid destruction order issues. This fixes
a leak of these objects, and eliminates an extra level of
indirection in Type::getInt32Ty and friends.
