Nick Lewycky c2ec0725ce Extend 'readonly' and 'readnone' to work on function arguments as well as 
functions. Make the function attributes pass add it to known library functions
and when it can deduce it.

Stephen Lin b8bd232a3d Add CodeGen support for functions that always return arguments via a new parameter attribute 'returned', which is taken advantage of in target-independent tail call opportunity detection and in ARM call lowering (when placed on an integral first parameter).

Michael Ilseman 516d70399e Cache the result of Function::getIntrinsicID() in a DenseMap attached to the LLVMContext. 
This reduces the time actually spent doing string to ID conversion and shows a 10% improvement in compile time for a particularly bad case that involves ARM Neon intrinsics (these have many overloads).

Patch by Jean-Luc Duprat!

Bill Wendling efbbbfd384 Don't assert on empty attributes.

Bill Wendling 1c20ff028e Add and remove the attribute from the correct slot. 
The slot that we're adding/removing the attribute from may not be the same as
the attribute coming in. Make sure that they match up before we try to
add/remove them.

Bill Wendling 49bc76cbb3 Remove the last of uses that use the Attribute object as a collection of attributes. 
Collections of attributes are handled via the AttributeSet class now. This
finally frees us up to make significant changes to how attributes are structured.

Bill Wendling 430fa9bfb3 Use the AttributeSet when removing multiple attributes. Use Attribute::AttrKind 
when removing one attribute. This further encapsulates the use of the attributes.

Bill Wendling c0e2a1f457 Use the AttributeSet when adding multiple attributes and an Attribute::AttrKind 
when adding a single attribute to the function.

Bill Wendling 09175b39f2 More encapsulation work. 
Use the AttributeSet when we're talking about more than one attribute. Add a
function that adds a single attribute. No functionality change intended.

Chandler Carruth db25c6cf8e Actually update the CMake and Makefile builds correctly, and update the 
code that includes Intrinsics.gen directly.

This never showed up in my testing because the old Intrinsics.gen was
still kicking around in the make build system and was correct there. =[
Thankfully, some of the bots to clean rebuilds and that caught this.

Chandler Carruth 9fb823bbd4 Move all of the header files which are involved in modelling the LLVM IR 
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Chandler Carruth ef860a2488 Rename VMCore directory to IR. 
Aside from moving the actual files, this patch only updates the build
system and the source file comments under lib/... that are relevant.

I'll be updating other docs and other files in smaller subsequnet
commits.

While I've tried to test this, but it is entirely possible that there
will still be some build system fallout.

Also, note that I've not changed the library name itself: libLLVMCore.a
is still the library name. I'd be interested in others' opinions about
whether we should rename this as well (I think we should, just not sure
what it might break)
