classes, per PR1324. Not all of their helper functions are implemented,
nothing creates them, and the rest of the compiler doesn't handle them yet.

using OwningPtr. OwningPtr would barf when the densemap had to reallocate,
which doesn't appear to happen on the regression test suite, but obviously
happens in real life :)

"half precision" floating-point with a first-class type.
This patch adds basic IR support (but not codegen support).

patch brings numerous advantages to LLVM. One way to look at it
is through diffstat:
109 files changed, 3005 insertions(+), 5906 deletions(-)
Removing almost 3K lines of code is a good thing. Other advantages
include:
1. Value::getType() is a simple load that can be CSE'd, not a mutating
union-find operation.
2. Types a uniqued and never move once created, defining away PATypeHolder.
3. Structs can be "named" now, and their name is part of the identity that
uniques them. This means that the compiler doesn't merge them structurally
which makes the IR much less confusing.
4. Now that there is no way to get a cycle in a type graph without a named
struct type, "upreferences" go away.
5. Type refinement is completely gone, which should make LTO much MUCH faster
in some common cases with C++ code.
6. Types are now generally immutable, so we can use "Type *" instead
"const Type *" everywhere.
Downsides of this patch are that it removes some functions from the C API,
so people using those will have to upgrade to (not yet added) new API.
"LLVM 3.0" is the right time to do this.
There are still some cleanups pending after this, this patch is large enough
as-is.

representing a constant reference to ValType. Normally this is just
"const ValType &", but when ValType is a std::vector we want to use
ArrayRef as the reference type.

cookie argument to the SourceMgr diagnostic stuff. This cleanly separates
LLVMContext's inlineasm handler from the sourcemgr error handling
definition, increasing type safety and cleaning things up.

obvious places to change say "do not edit this file".)

modules are also deleted.

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.

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.
