b27da4e9b4 switch IRBuilder to use NewDebugLoc for locations instead 
of raw mdnodes.  This allows frontends to specify debug
locations without ever creating an MDNode for the DILocation.

This requires a corresponding clang/llvm-gcc change which
I'll try to commit as simultaneously as possible.

96eb1c7f8f Switch the representation of the location in instruction from 
being a TrackingVH<MDNode> to a NewDebugLoc, shrinking 
sizeof(Instruction) a lot, and providing clients the ability
to deal with locations in terms of NewDebugLoc instead of
having to deal with Metadata.  This is still fully compatible
with all clients that *do* use MDNodes for everything of
course.

No functionality change.

ff4e2688f5 fix a bug in DebugRecVH::deleted/allUsesReplacedWith. If an 
entry in the Scope+InlinedAt drops to a non-canonical form,
we need to reset the idx member of both VH's to 0.

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.

27c9cacb63 add new apis for getting/setting !dbg metadata on 
instructions.  In addition to being a convenience,
they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

9ab48420db Fix a major source of compile-time slowness at -O0 -g by optimizing 
the storage of !dbg metadata kinds in the instruction themselves.
The on-the-side hash table works great for metadata that not-all
instructions get, or for metadata that only exists when optimizing.
But when compile-time is everything, it isn't great.

I'm not super thrilled with the fact that this plops a TrackingVH in
Instruction, because it grows it by 3 words.  I'm investigating 
alternatives, but this should be a step in the right direction in any
case.

624a31f2eb Finally land the InvokeInst operand reordering. 
I have audited all getOperandNo calls now, fixing

This time I did a self-hosted bootstrap on Linux x86-64,
with no problems. Let's see how darwin 64-bit self-hosting
goes. At the first sign of failure I'll back this out.

83ebc265b3 Reintroduce the InlineHint function attribute. 
This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.

0b2c2769ba Generalize target-independent folding rules for sizeof to handle more 
cases, and implement target-independent folding rules for alignof and
offsetof. Also, reassociate reassociative operators when it leads to
more folding.

Generalize ScalarEvolution's isOffsetOf to recognize offsetof on
arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr
to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.

Make the target-dependent folder promote GEP array indices to
pointer-sized integers, to make implicit casting explicit and exposed
to subsequent folding.

And add a bunch of testcases for this new functionality, and a bunch
of related existing functionality.

getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1) 
  to
  inttoptr (i64 0 to i8*)
from the VMCore constant folder. It didn't handle sign-extension properly
in the case where the source integer is smaller than a pointer size. And,
it relied on an assumption about sizeof(i8).

The Analysis constant folder still folds these kinds of things; it has
access to TargetData, so it can do them right.

Add a testcase which tests that the VMCore constant folder doesn't
miscompile this, and that the Analysis folder does fold it.

Also add code for pattern-matching these expressions, for clients that

expressions into an element count times the element size, to expose
the multiplication to subsequent folding, into the regular constant
folder.

fb10587e50 Kill ModuleProvider and ghost linkage by inverting the relationship between 
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

1882fba746 Change Value::getUnderlyingObject to have the MaxLookup value specified as a 
parameter with a default value, instead of just hardcoding it in the
implementation.  The limit of MaxLookup = 6 was introduced in r69151 to fix
a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
Making the limit part of the method signature makes it clear that by default
the result is limited and should help avoid similar problems in the future.
This fixes pr6126.

3b08c33f33 Remove dead debug info intrinsics. 
Intrinsic::dbg_stoppoint
 Intrinsic::dbg_region_start 
 Intrinsic::dbg_region_end 
 Intrinsic::dbg_func_start
AutoUpgrade simply ignores these intrinsics now.

Thanks to Jay Foad for pointing this out!
